I couldn't find the problem anywhere so i figure i'll make a new thread.

I changed my Transfer Case and Rear Diff oil and installed my downpipe on friday and this morning (saturday) i started the car and there was a weird grinding noise coming from the engine bay passenger side. Also when i take off from 1st (dead stop) i'll hear the same grinding noise. any help is greatly appreciated.

p.s. the car drive and shift fine other then the noises on start up and from a dead stop, car still pull hard through all 6 gears.

 

If it's a bad betal scraping sound it could just be a rock stuck in your bake shield, or the shield go bent when you removed wheels. It can them come and go as shield changes temp. Very common.

 

cool i'll check it tomorrow.

i actually notice that the sound is in sync with exhaust tone, like when i go from P to R the exhaust tone and rpm rises and that's when i here the scraping noise. so it got me thinking the downpipe might be loose or scraping against something.

 

99.9% sure this is to do with the downpipe install and NOT the fluid change.

 

haha yea i hope so. i'll check everything under neat when i put her back on the lift tomorrow for the tranny oil change.

 

I'm 100% sure this is the case too.

 

well everything looks find.... tighten up everything and the DP isn't rubbing on anything. the grinding/rattling sounds like it's coming from the belt and pulley area.

 

changed out the exhaust hanger bushing to a new stiffer one and quite like before again
