Hummer H3For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.
That looks scary. Do the engine mounts need to be changed also? (The oil pan is swinging over big time.)
Here is the thing. You asked a question about a "clunk" and failed to provide YEAR and MILES, which IS important to know what your problem(s) might be.

You should have a ((((((warning "brake squeal"))))). Replace those brake pads ASAP! My ears are still ringing listening on my 7.1 surround connected to my pc. Did you get under and inspect/check front diff bushings and propeller?
Thanks for the tip! I replaced the brake pads... They needed it
So I replaced the diff bushing with another one. I'm not sure if I did something wrong the first time round or if it was cheap ebay junk. I could only get another ebay one and the problem has gone. The first one only lasted 6 weeks before it failed. If this one fails I'm going to have to upgrade it.
So I ordered the Anchor 3120 & Anchor 3121 Engine Mounts from amazon. They are a little different looking than OEM but they do fit. Hopefully the quality is good. The left side one was missing a thread on top for a wire bracket so I added a M6 nutsert. It took me about 4 hours to change them. I had to remove the knock sensor on the left side to get it out and removed all the bolts from underneath the car. The right hand side was easier to get out. Most of the bolts come undone through the top of the engine bay.
My engine mounts definately needed replacing:
Nutsert added to top Looks differerent but does fit. Welding seems less than OEM Left side under exhaust was worst It was completely cracked
I have taken it for a test drive and the engine still swings under load. I will replace the gearbox mount as it came in a kit.
I will take it off road again and see if the knocking sound has gone. wish me luck
