Noise started out of nowhere about 1/4 mile up the road from my house, all was quiet then "wrrrrrr" incredibly loud like a coke can stuck in a bicycle tire..
Periodically when starting to back out of the driveway after sitting overnight there would be one light 'pop' in the rear, but I figured that it was just the rear rotors being rusted and stuck.
FRPP 4.10s installed at 40k, j-mod to the trans at 50k, has 81k now. Just have basic boltons and only ran on drag radials for 5 passes one day a few weeks back. Don't know what couldve gone wrong
It looks like the damage is only on the spider gears & possibly the side gears on the axles.. if thats the case, can I just get a new spider gear set? I turned the rear over several times and never saw anything wrong with the ring or pinion.
