70chevy03ss Posted May 3, 2009 Report Share Posted May 3, 2009 Torsion bar bushings. I have had a clunking noise under my feet as well. i did a lot of new parts in the front end last month and still have it. So yesterday I was under neath doing the oil change and I grab my torsion bar and that thing was moving up and down. I thought bingo now I need to get me some new bushings. Try that out.

Jaymz Posted May 3, 2009 Report Share Posted May 3, 2009 UJoints and wheels berings would also be on my list to check once I got the truck jacked up. Quote Link to comment Share on other sites More sharing options...
ssjeff71 Posted May 3, 2009 Report Share Posted May 3, 2009 I've had that problem with my intermediate shaft. It will make clunking while going straight...or at least it did on my truck. Simple fix that the dealer would charge a lot for. Un-bolt shaft either at sector or in the middle and slide it towards the steering wheel. It will push the heavy grease back up that has slid down due to vibration and gravity and you'll be good for another 20,000 or so. Quote Link to comment Share on other sites More sharing options...
RacerJJ Posted May 8, 2009 Author Report Share Posted May 8, 2009 Just a thought...could this be happening because my new wheels are NOT hubcentric? Quote Link to comment Share on other sites More sharing options...
RacerJJ Posted May 18, 2009 Author Report Share Posted May 18, 2009 Still there despite my best steering shaft stroke, fluid changes, and bushing/ball joint lubing. No there is some squealing/squeaking involved but everything is still intermittent. Is it my wheel bearings? Any ideas, please. Quote Link to comment Share on other sites More sharing options...
DOWNSOUTH407 Posted May 20, 2009 Report Share Posted May 20, 2009 I had a clunking sound when I would go over bumps or turning. It does not sound like mine was as loud as yours. Mine turned out to be a worn out idler arm and pitman arm. Good luck, hope you find it. Quote Link to comment Share on other sites More sharing options...
RacerJJ Posted May 22, 2009 Author Report Share Posted May 22, 2009 Well, the final verdict is in...my front diff is toast. Found huge chunks of metal when I did a flush of it today and it is still clunk, clunk, clunking away. So I am done racing until I can get her fixed or off load my problem on someone else. Question...has anyone changed their front diff themselves? Is it difficult? Is it something I could do in my garage? Quote Link to comment Share on other sites More sharing options...

Easy enough to do, you unbolt the front u-joint, undo the 1/2-shafts, undo the arm on the steering center-link so you can push it forward and get a couple inches more room, then undo the 4 bolts holding the carrier in the truck and drop it out. Sorry to hear about the damage. Mr. P. Edited May 22, 2009 by Mr. P. (see edit history) Quote Link to comment Share on other sites More sharing options...
RacerJJ Posted May 22, 2009 Author Report Share Posted May 22, 2009 Thanks P. Now I am just trying to decide if I want to fix it or try to sell it for parts so I can buy something different. My third option is to convert it to 2WD. Quote Link to comment Share on other sites More sharing options...
rwoodards Posted May 23, 2009 Report Share Posted May 23, 2009 (edited) I swapped my T-case and that fixed the problem. Check out my post. Klanking / Clanking Link Edited May 23, 2009 by rwoodards (see edit history) Quote Link to comment Share on other sites More sharing options...
