bumpity, bump, bump goes the bronco

Okay Gurus,

Here's one I've asked several people. After taking off from a dead stop, there are a series of "bumps" to follow everytime.

HAd the rearend rebuilt, transmission, and transfer too. The spring shackles seem okay. Driveshaft??? It is a bolt on with no greasefitting. U see what the advice from many people has already cost, so if anyone else has or had this problem, please share your solution.

Thanks

From the vauge discription it sounds like you're having axle wrap. Mine has that when I get on it a little because I never put back on my sway bar thingy on my rear end. Needs to be there though, I can feel the rear end move around corners! :-

Sorry, It's a 94 EB, all stock. The noise SEEMS like it's the rear end. ???? As I said, it was rebuit ( by a pro) I guess I'll look at the sway bay again, but it looked fine to me. Who knows.Thanks for the suggestion.

Hey I have a 95 xlt mine was doing the same thing when leaving from a stop it would make like a clunking sound or banging and you could feel it in the rear end I put a lift in with new springs and bushings and the noise went away people i know with Broncos said the same thing Has somthing to do with the rear shackle bushings getting worn out Hope that helps

Maybe the u-joints? I know I got a clicking noise from my "rear" till I dropped the rear driveshaft off and replaced the u-joints. Just my 2 cents on it.
