chicofuentes0224 Posted October 25, 2007 Share Posted October 25, 2007 Yep when I'm drivin at about 35mph and with the rpm's at about 2000 I sometimes hear a thump. Do you guys think It's a problem with the axle. It's coming from behind me somewhere. 1988 I6 automatic. Thanxs guys Link to comment Share on other sites More sharing options...

Thanxs guys you can pull the diff cover, won't take to long, and check the gears for obvious signs like missing teeth and stuff. refill with any 80w90ish gear oil Link to comment Share on other sites More sharing options...
chicofuentes0224 Posted October 25, 2007 Author Share Posted October 25, 2007 Man I love you guys. Such comedians! :D . So what tools do I need and where do I put the gear oil? Next if the gears are screwed should I get new ones or a new axle? Link to comment Share on other sites More sharing options...

chicofuentes0224 Posted October 25, 2007 Author Share Posted October 25, 2007 no but here's the wierd thing. I just dissconnected the ccv hose off the back. The smaller side connected On top of the exaust manifold. Not only does the truck idle and run better. It quit making that thump, and it shifts a lot better. :nuts: Link to comment Share on other sites More sharing options...

chicofuentes0224 Posted November 8, 2007 Author Share Posted November 8, 2007 That thump in the back is my exaust hitting the transmission crossmember. Maybe the tran. mount is out? Link to comment Share on other sites More sharing options...

Either that or your exhaust hangers are rotted out and broken. Either way easy fix. Link to comment Share on other sites More sharing options...
