OK my father in law has an 82 Scrambler and never drives the thing because it has no power brakes or steering. I am going to be borrowing it from him in a month or two and want to give it back with the power brakes and steering but am not sure of which parts to use? I have a donor YJ I can get parts from will they fit? I am talking things like the master cylinder, booster, power steering pump and brackets and gear box? Any help is appreciated. If those parts don't work what junk yard parts should I look for? I am not worried about hoses or lines as I have a buddy that makes them professionally.
OK I ripped everything that had to do with power steering and brakes out of a 92 YJ 4cyl, most of everything looked different than I had seen before on any of my jeeps but I figured what the heck. The scrambler sits about 120 miles from my house and the donor was 80 miles in the opposite direction so alot of this was based on hoping and the very little research I had done. So here are the parts the I had taken from the donor.
After we had everything out we compared what was in there with the parts I picked up from the donor and it looked like just about everything would fit. On the 92 the gearbox had bolted through the frame and then again into the frame but the CJ did not however we were able to put the CJ Brackets on the YJ gearbox and it bolted right in. The steering column bolted right in and the plugs fit and I couldn't be happier at this point until I went to install the steering shaft and it was an inch and a half to short due to the 3" body lift on the CJ. The old shaft was the proper length but it was splined on top and the YJ column was not so we switched back to the stock Column and the shaft went right in and also slid right on to the YJ gear box splines.
Now comes the Pump, I was most worried about this because it was a totally different style and looked nothing like any that I had seen before and it also had a remote resevoir. Well we got lucky and the bracket fit right on like it was meant to be there, the only modifacation needed was to space it out 3/16" so that the belt would line up. Here are some pics.
The hardest part about the power steering upgrade was running the hoses there just was not alot of room.
Also the original belt was 87" long and the stock one for my YJ was 81.7" long and both were to large, we ended up grabbing a 74" long belt that fit perfectly.
I will get more in the morning along with the power brakes.
That was almost an option a year ago when it didn't run and he hated it. Now everytime I visit I end up doing something to it and now it runs great and is plesant to drive so it will never be in my garage. out:
So I think this covers most of the power steering except for the resevior, since it was the style not built in to the pump I think this made things a little more difficult, I ended up having to make both new lines so that they were long enough, I don't believe these to are high pressure by how they were clamped by the factory but we use high pressure line anyway just to be safe. On the picture below we had to cut the hard line to the right and re flare the end because when left at the stock lencth it was hitting the lower radiator hose and I was worried it would eventually eat through it. We ended up mounting the resevior on the firewall below the the brake booster and towards the fender.
Now to the brakes. This is what was stock and I am sure most of you have seen and delt with this set up, It worked ok but with the 33's was not the best system around and heck if you are gonna do the power steering you might as well do the brakes as well.
We got lucky and his came pre drilled for the four holes it takes for the booster.
Here is the booster that I grabbed from the donor 92 YJ.
I grabbed the propartioning valve and all just in case. I here they are the same thing but for some reason the CJ one cost more and we deiceded to go ahead and keep the CJ valve mainly because it is mounted on the frame and would have been a PITA to swicth out. I followed the link posted way above for the YJ booster upgrade and went to Napa to get the two adapters needed for the brake lines and of course one was wrong. Since we did not have the correct fitting we had to cut the stock line and put one of the fittings on from the 92 on the 82's brake line and re flare it, this ended up being the easiest and best fix for this problem (If you have the tools). Now back to the 3" body lift, this came to another frustrating bit because the brake lines were already stretched a bit so we had to uncoil more than I wanted to get them to reach the opposite side of the MC. All in all this was a very easy upgrade and we were lucky as that the pedal assy fit perfect and our lights did not get stuck on and the brakes work great.
Almost forgot on the vacumn line once again I had to make it longer due to the body lift but attached it exactly how the link above shows. (You can kinda see it in my last pic)
All in all we are both very happy with how this turned out and it makes the Jeep much more enjoyable to drive. The steering feels like my 90 which is great and the brakes feel better than most jeeps I have driven. the only things that we will eventually change are the brake lines since they are stretched a bit more than I like and if I were buying junk yard parts I would have gone with the pump that has the resevior built in for the ease of not having to mount yet another part.
I owe a huge thanks to Yellow85cj without his suggestions and knowledge I would not even had tried it.
I used the CJ factory bracket but put it on the YJ gear box and the pump bracket fit fine but I had to space it out with a couple washers so that the pulleys lined up good.
I have an 86 cJ7 with manual steering, I just bought a power steering box off a yj..you said you were able to use the stock cj shaft and it fit the splines on the yj box?
Yes but it was a little tight I had to tap it with a hammer to get it on but it wasn't to bad at all. I think the YJ box had a flat spot for alignment but the CJ shaft did not but not a big deal at all.
Also if you get it done and you can only turn so far one way but all the way the other direction you will have to lengthen your drag link by loosening both the nuts near the pitman arm and turning the coupling.

Also if you guys are going to do the brake swap you will also have to swap the air cleaner from a YJ or CJ because the round one that sits on top of the carb will not clear with a brake booster in the way but the one that sits on top of the valve cover is an easy swap to do.
One more thing on the power steering pump I had moved the smog pump and had to make a bracket for that, It now sits where the AC would have gone in place of the extra pulley most of us have on the top left. I will try and get pictures of the whole set up next time I am near the jeep.
I was going to change it and no they are not the same. The YJ one has a D shape connector with no splines on it and the CJ one has the round connector with splines. I was told before hand that I would have to swap out the whole setup so I picked it up and it would have worked perfect if he didn't already have a 3" body lift because the YJ shaft was to short. Th CJ shaft was a bit longer so it fit but where it connects to the steering box was a bit different but still worked, All in all it would have been better to use the YJ column shaft and gear box but it still worked fine with the CJ column and shaft, like I said before it was just more of a struggle to get the CJ shaft to connect to the YJ gear box but was not impossible. There may be some different setups in YJ's that are the same as a CJ but I know for sure the 92-93 power steering off a 4cyl YJ is a bit different than a 82-83 CJ8.
No smog pump or air cleaner worries..I'm running a small block chevy and no smog here in Indiana! On the shafts did you try to use the cj upper splined shaft and the lower yj dd shaft..as far as so called splicing them together I've read somewhere that it works
If what I did wasn't going to work then yes I would have chopped them both in half and sleeved and welded the two together. This is really not a hard project we had two of us working on it and it only took about 5-6 hours, the hardest part was running the power steering lines they never seemed to want to sit in a good place just something you will have to play with a little. Now that it has been done for a few months it is just a fun vehicle to drive and wheel.
I don't know for sure so maybe some others will chime in but from what I have seen it looks like it will but I have not done much work on any jeeps older than the 82.
I would assume so but I don't know for sure, I assume the pump will be the same but you will have to look at the gear box but I don't see why they would change the design. I think they are all basicly Chevy gear boxes anyway.
Hey chris from what I've read the cj manual coupler is a 3/4 36 spline and the yj box is 3/4 30 spline..that's why there was so much resistance to install it..has it held up good for you because I'm gonna try it..or if you still have the yj shaft I'd be interested in buying it..PM me
You could possibly be right but it didn't feel that bad but yes it is holding up fine.
