Chatter

When I take off from a stop I'm hearing a chatter that seems to be coming from around my transmission. (it sounds to be right under the shifter) I'm not sure if it is a broken mount, a bad u-joint, or a noise coming from the transfer case. Any ideas?

I am not trying to hijack your post or anything, but I was fixing to post a very similar question. Mine is only occasionally when I take off, probably about 10 percent of the time. It makes a clunking sound that sounds like its coming more from the rear of the vehicle and I was thinking possibly u joints but don't really know how to check or where to start looking? Any help would be great!!

i have the same after i installed the BB. it happens avery 10th to 20th take-off and most of the times in curves.
could it be posible, that the geometry of the suspension is wrong after the BB because of the too short track-bar for the lift?



@crj101: which tranny do you have? i think a u-joint could cause the sound.

That's exactly when mine happens. I noticed it friday when I had the wheels cut a little and started to take off. There is an exit ramp off the interstate turning right that it always happens on. Did yours get any better once you installed longer shocks becasue that's something I still haven't done yet.

after installing longer shocks nothing changed.
i have this sound since i installed the BB last june. it didn´t change anything since then.
so i think it´s ok...no...i hope that´s ok.

Yeah I hope mine is ok too. I could almost feel it today when it was clunking when I took off. I really don't think it's too serious or it would do it all the time i would think.

i agree. it does happen in so many different situations. sometimes 20 times a day and sometimes not for days.
that can´t be very serious...

Check your tranny mounts. Sounds like you might have a couple that are going bad.

The tranny mounts that mount to the frame or where the transmission mounts to the skid plate that protects it and the transfer case??

I HAD THIS PROBLEM OR SIMILAR
Turn on 4hi and see if it makes the noise again. If it goes away its the bushings on the transfer case linkage. Torque shaft... http://www.4x4xplor.com/T-CaseTSB.html

The tranny mount is on the bottom of the transmission and bolts to the belly pan. The stock rubber mounts have a tendency to dry out and crack which will give you some movement in the tranny/tcase.

there is a good chance that may be it. MR. CLIFFORD told me to loosen those bolts and let it run for a few minutes to help with some driveline vibes and I don't own a torque wrench so I might not have gotten them tightened back as well as I should have. I will check it tomorrow. Thanks
