Newbs here looking through posts and was unable to find one but wouldn’t mind being directed to a previous one or an answer if you’ve had or heard of this issue. When I come to a complete stop as the vehicle stops the rear has a clunk. When I accelerate as usual it does the same thing. If I feather the pedal lightly from a stop it is very minimal if any. I thought is was slack in the driveshaft at the rear but was told it could be bad shackles. If the shackles were bad wouldn’t I feel the clunk as I drive and hit bumps? It only happens when I accelerate from a stop and right as the vehicle comes to a complete stop. Any with full size blazers 92-94 replace their rear shackles yet because of this issue? 92 blazer

 

Sounds like a bad ujoint

 

it does not make a clunk when I put it into gear in drive or reverse or when I power brake. It only happens when the weight of the vehicle shifts out of a stand still or into one though. Could that still be a bad u joint?

 

The slip yoke on your driveshaft may be worn and hanging up a bit.

 

I’m going to grease the **** outta the slip yoke tonight and see if that makes a difference, If it does than that’s it good call. I’m hoping it’s not the u joint but either way I gotta get this beast completely dialed it right as I bought it for my wife as a daily driver and she’s in love with it more than me because no car payments and I’ve convinced her I’ll be able to fix Anything that goes wrong. That’s going to be put to the test for sure.
