Hi there
I have a sound that I am looking into. Its kinda grinding, growly sound. It happens on lower speeds during deceleration. I thought it was the brakes but its coming through the shift lever hole so I think the driveline is the place to look. This includes many things including the exhaust.
So far I have checked,
- the brakes- rotors turned, new pads, calipers rebound, no chattering
- driveshaft flange bolts were tight
- centre bearing- new and seems fine
- u-joints- new, front seems fine, one axis of the rear u-joint is stiffer than the other axis/going to get the driveline shop to do a warranty check.
- tranny output shaft-driveshaft bushing- cleaned and greased
- guibo- new and bolts/nuts correct n tight
- tranny output shaft/flange- no leaks, no slop, output flange tight, tranny smooth
- driveshaft slip joint- cleaned and greased, nut tight
- no rubbing between shifter support/mechanism and guibo
- engine and tranny mounts- new and good
I have not yet checked,
- diff- input flange, pinion bearing
- exhaust- the rear flange of the front muffler has about 1/4" clearance to the driveshaft; there is very slight sign of a rub on the driveshaft but does not look like it would result in the sound. To test, I'll hang it a lil lower when reassembling.
Its a surprisingly long list to check. Any insight you have Forum is appreciated!? I feel it will be something simple.
Regards,
Bill
