i spent around $75 between needing a new tail cone, and replacing some worn out parts like bearings seals and shift fork pads. ooh and $50 on the 231. so around $125 total. so, if your doing it your self expect to spend anything from $100 to $300 depending on how much you pay for the t-case and wether or not it needs a rebuild, most rebuild kits range from $75 to $125 depending on how complete they are. JB conversions sells the most complete rebuild kits BTW.
Depends which 242 you want. The 4.0L 242's (27 spline) are readily available and cheaper than the 242HD (32 spline). When my 242HD recently took a dump, I sourced a low-mileage 4.0L 242 for much cheaper than the more sought after counterpart. Just swap the input gear from your 247 to the 242 and you're set.
Or, like Sandman said, 231's are even cheaper (and more aftermarket options), but take a tad more work to fit in a WJ.
Before I get any further in this, how hard is it and what is involved, I could swear I saw a thread with a transfer case swap around here but I cant find it now... This will be the first real project I have done to the jeep, only thing I have done before was the budget boost, so sorry if Im slow to catch on to what is needed...
So the 231 doesnt have full time 4WD right? So I am wanting the 242.
What 242 works with the V8 4.7L, 32 spline 242HD is best right? I see alot listed for 4.0l, but few if any for 4.7.
The regular or HD version are both stout cases. The standard 242 is better in some respects actually, considering the HD has a longer tailcone which increases the angle of the driveshaft, plus the SYE options are extremely limited for the HD version.
Like I wrote in my post, the standard 242 requires you to swap the input gears from your original case to match the tranny (input shaft is longer). Not a big deal, but depends on your skill level.
