Hi I have a 2007 escalade. When i take off aggressively it gives me a loud clunking noise. But only when i take off aggressively. Otherwise it drives absolutely fine. if i'm on the freeway and I punch it there is no clunking. i've replaced ever front end part on it that can be replaced. Every bushing that can be named. every tie rod, control arm, axle, every mount and bushing. changed the differential and the differential mount. Anyone have any ideas?

 

What is the difference between taking off "aggressively" and punching it? I understand what punching it means but you say there is a clunk with an aggressive take off but not when you punch it. Is it a continuous clunking or just one big "clunk"? If it's one big clunk, does it do it when shifting from 1st to 2nd? A hard shift in the transmission will make a very noticeable clunk, which is not necessarily a good thing.

 

Check your universals. You may also have to grease your splined yokes.
