clicking sound when accelerating in 2wd & 4wd

[Pwnedheadnad]

i have a 1993 jeep cherokee 4wd, 5 speed, 4.0 engine. when im in 2wd or 4hi or 4lo and i take off fast there is a clicking sound coming from either the trans, transfer-case, or front end. it only clicks a few times then stops.

U JOINTS!. had the same problem with my 94. under heavy acceleration was the only time. "thought" my ujoints were fine but when i did my lift kit the rear driveshaft u joint that goes to the differention pracitcally fell apart so. make sure that you take a look at those and make sure there is NO movement. if there is, replace. theyre only like 15 bucks from napa and easier to change than the front axle u joints.

thanks for the idea but i just check my ujoints and they are solid, no rust or movement. any other ideas?

Solid with no rust or movement was how mine were before I replaced them....and my clicking went away. The inside is the important part and a visual inspection won't see that.

How many miles do you have? If it's more than 90K and you haven't replaced the U joints, then I agree 100% with soldierp89.

The only other thing I can think of that clicks under acceleration would be a broken wheel stud.

my jeep has 135,000 miles on it and the guy i bought it from was not a mechanic of any sort. are you saying both my front and rear ujoints are bad?

Nope, not saying both are. It's likely it's just the rear, since most 4wd vehicles aren't in 4wd all the time.

IMO, replace the rears and then reevaluate.

i had something weird happen today. i was driving and i smelt a bruning smell and when i braked the jeep would veer off to the left. i just put need pads and new rotors on both front wheels. then i shut off the car for a while. then later fired it up and drove 8 miles without a problem. what could that be?


thanks

possibly one of the calipers wasn't reinstalled correctly i know it sounds far-fetched but i've seen it before the caliper overheated then by some overwhelmingly confusing way that is completely beyond me it managed to realign it self
