87Chief Posted February 28, 2011 Posted February 28, 2011 When I go about 25-30 mph I shift into 3rd gear, I hear this kind of grinding noise from tailpipe (well back on truck, heard with window open).. But once I push the gas more, it goes away, then let off it comes back.. It does this in 4th too... It usually happens about 15 minutes of driving... Any suggestions? I brought the truck into class to look at it and the exhaust wasn't welded on to the pipe, just had muffler clamps, my instructor welded it and we did a smoke test to make sure no more leaks, but this still happens... (it was doing th noise before this too...) Thanks
Dirteatr717 Posted February 28, 2011 Posted February 28, 2011 Check your hangers or if you still have your spare mountedcheck to see if it's tightened up enough?:hmm:
87Chief Posted February 28, 2011 Author Posted February 28, 2011 How do I check the ujoints..? Is there a certain way other than just looking at them? lol Do i shake it up and down, left right? Thanks
87Chief Posted March 3, 2011 Author Posted March 3, 2011 I'll be bringing it to school tomorrow. If I get a chance to bring it in the shop. What should I look for/do for the problem?
