Hey guys, so I've determined I have got a bad VC in my 249 (tires squealing/binding while turning, etc) but I like my 249 and plan to keep it and soon just replace the VC (will probably pull case, so I can also replace seals too). However, in the mean time while driving with a bad VC are there going to be any other negative consequences, or will it wear anything else out until its fixed? Also, since its bad, does that mean I won't have properly functioning 4x4 until its fixed?
Since I also have a '97, i was planning on removing the front drive shaft to stop the binding and squealing when turning until I fix the VC, but I noticed I have the cv-style front drive shaft, and was wondering what the process was to removing it, and if it would have any adverse reactions from removing it, like losing fluid, letting in dirt, etc.
It will just wear out your tires faster driving with a shot VC. I dont know about removing the front CV DS for sure since I have never removed mine fully but I think you can take it out without leaking fluid from the front diff.
If I was still in the snow belt I probably would have replaced the VC in my 249 but I am not right now so I swapped the 231 in and happy I did. Drove for over a year with a shot VC.

You will have a too- well functioning 4wd when the VC goes bad. It pretty much sticks close to 50/50 torque bias and kind of locks, so it's closer to 4hi part time than AWD. That's why you get the tire squeal and wheel hop. It does cause all sorts of extra stress on drivetrain and steering parts.
I suggest removing the front DS until VC is replaced. IIRC six or eight bolts on the CV joint, four at the TC end. Straightforward job really.
Pulled that front shaft this morning, pretty easy, 6 8mm bolts on front, 4 8mm on rear and a gentle smack and it came right out in less than ten minutes.
Needless to say, best things I've done so far. This is probably a bad thing it responded so well, but what an amazing difference it made, steers and corners better, quieter while driving, smoother acceleration and less of that dragging feeling, and mpg even improved some (I know this is not a mpg-improvement mod, but with the VC being bad, the extra stress it was causing was actually killing a few mpg, and removing it freed them back up). Thanks for the help here guys, gonna start saving for a new VC now lol
I know i have a bad VC in my 93 ZJ but can it cause just one tire to wear faster then the rest or is it an alignment issue?
On mine its the right front tire that has the most wear on it (if the other three are at 80% left this one is at 45-50% left)
Yes it can. this is the spinning tire for the front end. Just like with the rear it will be on the opposite side of the vehicle. Rotate your tires. Put this tire on the side that is not your spinning tire. It will wear faster in the front because unlike the rear the front turns.
Since you have a pre 96 your pulling more from the front now with the bad vc.
This tire is the one you don't want to sink in the mud until it can spin freely or your stuck. It requires tension to engage the other tire. Although polka tells me to apply the brake lightly and the others will engage. Sounds like common sense right lol. Wish I had thought of it at the time.
