Have an 87 s10 blazer 4x4 that has a 3" lift. The other day
while making a u-turn I heard a rubbing, creaking sound coming
from front end. Assumed it was the plus size tires rubbing
on the fender well, as it does sometimes with a sharp turn.
But once I got it home I noticed the right side, (looks like the
front moreso than rear) is now sitting lower than the left.
The shocks seem just fine. Runs just fine, but goes
'thunk' no bounce over any type of bump. Any ideas?

 

did you check your spring seat sometimes if the spring isn't seated properly it can create a clunk also check your ball joints for excessive play if you replaced them with the lift but find that they have excessive play they might allready be bad or diffective one other part to check is the shock out of the vehicle therefore taking away the spring to test the shock on its own you might have an internal seal blowout or there's a leak also check the rear of the same side another way to test the suspension is with a bounce and rebound check by depressing the corner making the noise up and down by your own force try to recreate the noise with the vehicle off and you right by the corner that it is clunking in doing this should bring you to the conclusion of what is causing the problem
