Another WJ (99-04) Grand Cherokee Seat Swap into a TJ

My stock seats were pretty beat up due to age, weather and constant wear from the previous/ original owner. So I went out to the local Pull-yer-Own and found a totaled out 99 Grand Cherokee. Seats were in pretty good shape, so I picked them up for a $100. Manual adjust, cloth, no forward tilt. Nothing fancy. The one thing that I was really hesitant about on Grand Cherokee seats was the loss of the Forward Tilt since I have two little ones that I constantly get in and out of the back seat from either side. Luckily this was an easy fix as well!
So, for the swap of the seats, it is pretty basic. Remove stock seats from your TJ, remove frames from bottom of your TJ seats (sliders and all), remove stock frames from WJ seats (discard), install frames from TJ onto WJ seats, install WJ seats with TJ frames into TJ Jeep, go get 'em dirty. (Actually you have to notch the plastic covering on the side too, but I'll get to that later). All in all, if you can find a set of these guys lying around in a junkyard somewhere, I'd say go for it. They seem to form around you better than the stock seats do (a little bit) more like a sport seat does, but cush enough to still be enjoyable! I give it :2thumbsup:!
Now for the added goodies that I found....
If you are considering the WJ seat swap, and are hesitant because you want to keep the forward tilt, YOU CAN! The hinge on the side of the TJ seats are the EXACT SAME as the ones for the WJ seats, but have the release lever on them. All you have to do is remove the hinge from the TJ seats, and swap them over to the WJ seats. Cut a 1" slit for the lever to poke out of in the back of the seat, and WAH-LA! 4-bolts. One 1" cut and That's it.
So, let's get into details, shall we?
So after a good (and MUCH needed) steam cleaning this is what I've got..... (The one on the left was still a little wet)
Image

So here are my new (to me) donor seats from a 1999 WJ Jeep Grand Cherokee. Manual adjust, cloth, non-heated, and CHEAP!
So I removed my driver seat and frames from both WJ and TJ seats. Here are the side-by-side comparisons.
Image

The WJs look to be a little shorter (only 1" shorter with the headrest ALL THE WAY DOWN!) but they really aren't. Optical illusion.
Image

Now the BOTTOMS of the seats look a little taller on the WJs from this angle, but that is not true either. The base (where your butt sits) is actually even with the TJs, but the sides are a little more supportive and not as flat. More of a bowl than a plate shape. A feature that I was looking for in a new seat. (More support, or "wrap" I like to call it)
So I was about half way done with the Driver seat swap when I thought about the forward tilt.... and a light bulb went off...... "I wonder if I could retrofit the unlocking mechanism in the hinge on the TJ seats onto the WJ seat hinge?" When I pulled up the upholstery on the TJ seat and the WJ seat, I stood back and thought.... "Hmm... that looks REEEALLY SIMILAR!!" Now, the pictures below are from the passenger side. I had to make sure the hinges worked and fit correctly prior to taking pictures.... didn't want to steer you guys wrong, so NOTE: THESE PICTURES ARE OF THE PASSENGER SIDE Driver side is done the EXACT SAME WAY.
Image

THEY ARE A DIRECT SWAP!!!
This is how to remove them from the TJ seat (passenger side is shown). Install on the WJ seat is the exact same, in reverse of course.
There are four 13mm bolts holding the hinges in place. There are no other bolts in these hinges, so you can't miss 'em. (In the pictures, the 2 bolts in the bottom half of the hinge have already been removed). Two on the base of the seat,.....
Image

Image

two on the back of the seat.
Image


Another note, on the PASSENGER seat, due to the forward TUMBLE cabling, there is a cable with a connector (similar to a throttle cable) hooked up to the back of the hinge that connects up to the pull tab on the top of the seat. This cable will be removed from the hinge. I did not retrofit the pull tab up top into the WJ seats so the cable was left in the TJ seat. This cable is not present on the Driver side.
Now, once you have your hinges installed, the plastic trim piece you removed to get there has to be trimmed. It is about a 5"x2" cut. I cut mine at an angle towards the front, not really sure if it was needed to be done that way, but cut it small, and make it bigger if need be. I used a hack-saw. Took (LITERALLY) about 20 seconds to cut this thing out. Both sides were cut the same.
Image

Now the plastic covering does rub on the roll bar a VERY little bit when the seats are pushed all the way back. Here are pictures of the lack of clearance on both .... Driver side (pushed about 75% back)
Image

And Passenger (all the way back)
Image

And here's the finished product
Not a PERFECT match, but dang near close enough for government work!
Image

And here is a picture of the WJ seats with the Forward Tilt in action! (Seat was pushed up pretty far when picture was taken. Had to get access to rear of seat to remove plastic trim piece for pictures a little further down in the thread.)
Image

If anyone has any questions on this swap, let me know. If something is unclear, please let me know and i can try to clarify it up best as I can. I hope this helps some of you guys (and gals) out! It's a pretty simple, straight-forward swap, including hinges, and I think just about anyone would be pleased with the results. Thanks for checkin out my first write up! ENJOY!!!

Wow, I bet those are alot nicer on bumpy rides! Do you have pict from a couple feet back (over view) I'll be grabbing some of these whenever I go to the P-A-P.

Also, nice Goat!! love those things
Ya know, I haven't really had the opportunity for long or bumpy rides yet, but I am confident that they will meet my expectations.

And the Goat!? That's my toy... got it from a guy in Houston who bought it "just to see what it could do." Did all the engine work and everything to it. Where does it sit? 475 RWHP/467RWTQ.
Image
Needless to say, it's fun!!! (And MAN are the seats in THAT comfy! I considered putting a set of GTO seats into the TJ, but they are 1.5" too wide on the base.... or I would have!)

Awesome write up, brother! Looks like you used a whole roll of duct tape on your old seats... great job on the "new" seats.
HA! My brother was asking me why I wanted to replace them. I was laughing at him! The previous owner was the "Upholstery Repair Man," though it was a FANTASTIC and very professional job well done!

whar was wrong with the factory seats?

jk, looks good bro.
See above reply.

Also added in the finished product photo at the end.....
(There was one small tear in the bolster on the driver seat that I sewed up, that's why it looks a little bunched there)

What a great job on installing those seats in your jeep and on the write up :2thumbsup:...now I am going to keep my eyes open when I am out at the local Pull A Part. My driver's side seat has a few feet of duct tape holding it together as well. :D

The plastic piece covers the bottom half of the hinge. I'll remove it when I get back to the house (in @ an hour) and I'll take a picture of the seat with the cover off. It is mainly cosmetic, but I also think it will help keep little wandering fingers out of potential hazardous and painful places.

I hate to admit it, but I don't wheel it much. I hope I can get to start though! And in regards to keeping them clean... I am in search of some neoprene covers for the front WJs and (hopefully a matching) TJ rear. I think that should do the trick. Any additional input from you guys would be helpful.

Very nice install!

I remember being at work the other day and driving a WJ into the shop for something or other... I remember thinking "man these seats are comfy" :D



Any clue if the bottom tumble portions of an 03-06 seat is the same "bolt pattern" to bolt to those as well? I know the seats changed from 97-02 vs 03-06... but not sure how much of it changed on the bottom/insides.

Thanks! I'm liking them up to this point.
For the 03-06 TJs, my understanding is that the brackets bolt to the base of the seats just a little differently, so some fabrication will be needed. Not sure how in depth that would be, but that's what I read.

Now I REALLY need to look for a set!!!

Thanks for the write up!!!

Sorry for the delay guys, I guess I unsubscribed to my own thread! :shhh:

Comfort is much better than the stock TJ seats. If I were to change anything with them, I would throw a little extra padding in for some lumbar support. I'll probably put some neoprene covers (or something similar) on them to help the tanish-grey match my slate grey interior a little better. Other than that, I am definitely happy with the swap. Money well spent.

In a few more months, once spring-time hits and the weather gets back to be a little more consistant and warmer for the kiddos, I'll be taking the wifey and kiddos out on some wheeling trips. Once that happens, I'll get a good "day-long-ride" review for everyone. :thumbsup:

Awesome thread...

Thanks for this post! Just did the WJ swap into our '99 TJ this weekend. The seats are awesome and comfortable compared to the factory TJ seats. Just had the wife screaming as we went through the snow. Your post was the reason we made this switch. Thanks again!!!:2thumbsup:

Wonder if something like this would work on a yj. The design looks similar

I'm sure a little fab work could make it fit! That or a BFH!

I would think if you did this and added some seat risers you may be able to clear the seat belts without cutting the plastic. I know on my 05 I installed 1.5 seat risers and it made a HUGE difference vs sitting on the floor. If the WJ seats don't sit any higher than the stock seats that maybe an excellent option.

I was considering taking the seats out of my son's 2002 Grand Cherokee (he has pretty much destroyed its value :mad: but I noticed his seats have zero bolstering/enough of a bucket seat shape to hold my butt in place as well as my TJ's seats do. I'd like to do this some time and will when I find JGC seats that are shaped better. I especially want them because many JGC seats have heaters in them. :p

I think you'd be pleased with the JGC seats in the TJ. I've taken it on a few-hour road trip a couple of times and they are MUCH more comfortable than the stock TJ seats. Now, it's put more focus on me needing to fab up a dead pedal for the chronic "left foot's asleep again" syndrome.

I've heard it's a pain to get the wiring done up CORRECTLY for the heated seats due to them being controlled by the ecu (?). If you just wire them up directly, they can overheat and burn out sooner, burn YOU as well as being a fire hazard. Again, this is just what I've heard/read. Not sure if this is a true statement or not, but I think it is something to research prior to making a decision. I know you can find some fairly inexpensive aftermarket heated seat panels to retrofit into the JGC seats that are completely stand-alone. (Seen some pretty clean/ stock-looking installs with them too!)

Thanks for the write-up. I just put WJ seats in my TJ tonight. They are electric though so I have to get everything wired up yet.
If you want to do a write-up with the wiring, I'll post it up in the first post. That way it'll be easier to find if anyone else is interested.

I know this is an older thread but great write up. I found a set of seats from a 99 WJ and it is a huge difference from my old vinyl seats. After reading the first post it maybe took me a little over an hour to do the swap.
Glad to hear it helped. The seats are a direct swap and definitely an upgrade in my eyes. I've had them in for a while now and am very pleased with them. They've been out on several wheeling trips and have not disappointed. I recently took the covers off and threw them in the washing machine too. I would recommend that to anyone that buys a set of these. These things were FILTHY!!! It does take a little bit of time to remove the covers just because of the ring clips they use to hold them in place, but worth it in the end. Plus it adds a nice "spring scent" to the interior! LOL

FYI- you may not HAVE to remove the backing from the base of the seat to pull the cover, but I completely removed seat from floor pan and fully disassembled the seat to get them off. Made it a little easier I think.
