Transfer case buying question

I'm looking to swap out my 249 transfer case to a 242. I want to know what everyone's thoughts are on buying a used one, with say around 100K miles on it? I know the new ones can cost up to 1,500 but there are plenty of junk yards that have the 242s but they have about 100K miles already on them. Is it safe to buy those or should i be looking at ******* 600-1500 for a newer one? The junk yards are only asking about 250 or so for them.

search, there's ton of threads that will help you decide if swapping is the right thing for your driving/offroad needs or if you should rebuild. For example. go read this whole thread, then search for any new questions, and if you still have questions then come back

I see your point but I've had the select track in other jeeps and I've loved them more than what I have now. That's why since my VC is going I am thinking of just swapping out to the select track. So is getting a 242 case (the select track one) with a little over 100K on it ok or should I look at dishing out a lot more and getting a new/refurbished one?

I went with a jy 242 shelf unit w/90 day warranty for $275 and seems to work fine. No idea what the mileage was and it was a direct replacement for the 242 on my 96 4.0 which was fried.

I picked up a 98 242 out of a 96 ZJ at the junk yard. It was all nice and rebuilt already. The biggest thing is the chain with them. There really isn't an easy way to test to make sure it's not stretched though. Shift the transfer case and make sure you can get it into all the positions and that the outputs work properly relative to the input for each position. That's more or less the only thing you can test with it at the junk yard. I'd say picking up a JY 249 would be a bigger gamble than picking up a JY 242.

I got a used one through Advance Auto, it was clean when I got it, discovered one stud had been tweeked a little which hung me up during the install. Easy fix. It also had a small leak where the case halves join(not enough to worry about, after 6 months it hadn't leaked enough to even notice) All new seals had been installed when I got it. Paid around 300-350, with a warranty. Performed flawlessy, still working great when I totalled the jeep :-(
YMMV.

I've paid $50-$100 for 231s and 242s. Craigslist from people parting jeeps.

Ouch. T-cases in other parts of the country are kinda spendy. Around here the going price at the JY averages about $75 plus a small $15 core charge. There's a couple of yards that do half off days, so even though I ate the core charge (didn't bring it back soon enough) I got my 242 w/bezel for only $45 with tax.

I got lucky, as there were quite a few ZJ's with 242's in the yard I went to and pretty much had my pick of 'em. I chose the one that looked cleanest on the outside and didn't leak from the case halves. It cycled through all the gears fine w/o binding and none of the mounting studs were bent, also when I drained the fluid out of it, it was a nice red color and didn't have any metal shavings in the fluid either.

I have thought about replacing the chain just to CYA, but since I haven't had a chance to run the t-case yet I'll wait to see if I get an chain slap out of it before I split the case. I did however pick up new trans output seals and t-case seals to toss in when I do finally get a chance to swap it out.

If any of you guys need/want some 242 bezels, I've got 3 or 4 that I've picked up over the past few months.

This^^

Buy a decent used one and figure an add'l $200 for a new chain and master rebuild kit. Take a day to tear it down and rebuild it.

You could be well ahead with a rebuilt 242 with ~$300 investment.

This... And ignore the 242 haters out there. They know not of which they speak.

Same can be said for 249 haters...don't be jealous because my chains thicker and case is stronger. Lol

Sure, the 249 may be rated for more torque (1800 ft. lb. for 93-95 and 2030 ft. lb. for 96-98 as compared to 1486 ft. lb. for the 242), but in reality they're all rated for GVWs up to 5500 lb. Not to mention, a 5.2 has how much torque? 300 ft. lb. First gear has a ratio of what? 2.740:1. Multiply that out. What do you get? You get a max torque of 822 ft. lb. Even after you take the torque converter into consideration, you're still under the upper limits of the transfer cases.
I'll quote myself from another thread... These numbers are all taken from a NP/NV transfer case chart. The transmission ratio was obtained from numerous sites. Both the 42RE and 44RE have the same gear ratios. Strength is a moot point. Yes, it's stronger, but for what purpose?

"Case" as in housing or the transfercase as a whole?

Reason I ask, i'm about to assemble a 242-249 hybrid using the 249 front housing. I'm also going to look into the possibility of using the 249's chain and associated gear/output also. Just wondering which if any parts are stronger..
