Ok, I have a 1993 grand cherokee laredo, everytime I make a sharper turn it makes a horrible popping noise in the front end and the front tires start pulling. Its all time 4wheel drive, but as far as I know it shouldn't be making that noise. Any ideas on what it could be are appreciated!
You put 3 key words in the same sentence- sharp turn, front wheels pulling, and full time 4WD. Could be symptoms of a bad viscous coupler in xfer case. Bad VC's do not allow slippage and basically lock up the drivetrain when you put the truck into tight turns. My VC was so bad it started plowing by dad's shell driveway when I turned it around. Try doing low speed figure 8's in an empty parking lot to check your VC. If you hear wheels chirping- bad VC. Bad VCs are hard on drivetrain parts, especially CV joints. Your CV joint may be on the way out. If you have busted boots on your joints, replace the axle shafts on both sides. However, consider looking at your VC as well. It could be contributing to premature drivetrain wear.
Was the guy you bought the Jeep from a Jeep enthusiast? I'm not saying that you are at all, but VC's are easily hidden from unscrupulous buyers, and sometimes owners, because the symptoms are not constant. A quick test drive around the block will not sort out a VC coupler problem. Its only in those tighter turns do the symptoms present themselves. Now, if they owner did his research or had the vehicle looked at by a mechanic and the VC was bad, the part is $400 straight up, without labor, and maybe this is how you came to purchase the vehicle? How long have you had it, how long has this popping noise been present and did you get an unusually good deal on the ole ZJ for the mileage?
Knocking noise would typically be the front CV's. I'd describe a bad VC as a bucking when turning. Both mine and my Dad's ZJ need the VC's repaired one way or another..... but I just did the CV's on my 94 and that fixed my knocking noise.
Yea, I was hoping it wouldn't be the VC for you but it sounds about right. Clicking and popping would be bad CV's. When the VC goes it hops and bumps in turns and will wear out the outside of the front tires faster than normal. You can continue to drive it like that but eventually it will totally fail. New VC is about 300 bucks. A 242 or 231 transfer case is under 200. You could swap one out for cheaper than it is to repair the 249. Another thing to check are your ball joints to see if they are worn out.
Yep- another key word "parking spots" for bad VC. VC's bind up the drivetrain and the CVs take the brunt of the force in and out of tight areas like parking spots. No doubt CVs are your problem. Replace them and ride, but undertsand that VC could still be the root cause. Good luck!
Like everybody says, its the VC and your cv boots are probably next. My step dads 94 5.2 has a fried VC and just driving with it like that has fried the cv boots..Thankfully we're getting rid of that thing soon.

Ok guys thanks tons I'm gunna have it checked out by the mechanic I got it from and have him check the things you have suggested here...I just don't want something bad to happen and cause me to wreck with my babies in the jeep with me
Ok guys, before I could get the mechanic to look at it, it rained lastnight and I drove it thismorning, and now it isn't making the popping noises mentioned earlier....maybe something just needs to be greased??
Haha I had a ZJ with many popping cracking and knocking noises. First it was the u joints then it was the bairings so I finally got pissed off enuf that I had both axles and the drive line rebuilt to clean up the sound and it worked allot of the sound out of it all just so still have a popping sound in the front end when I got to the bottom of it it was as simple as whenever I would take a sharp turn the coil springs would flex and slip over the bump stop. Fu** me, right. Atleast after all that the jeep was great!
