Rear End Problems
I was think the gear oil needed changing so I went ahead and changed all the fluid in the drive train......
I was running redline gear oil before,,,,This time I went with Lucas high performance gear oil thinking a heaver oil would be better....It said on the can that no Additive was needed......((((Contains "climbing additives" that insures total lubrication. Expect less gear rattle,,,,less whine and longer bearing life)))) so I didn't put any of the GM additive in there.........Was that a mistake???
The Lucas oil didn't work to well for me,,, the problem has gotten much worse almost to the point where the rear end is locking up completely........
When I took the diff cover off there were no materials or any sign of wear,,,,That said I really didn't know what I was looking for anyway....So does anyone have any ideas to what's going on here?? I guess the next step is to take the diff cover off to see what's going on,,,,, any tips on what to look for??The car has 74,000 babied miles on it,,,, sets most of the time...........Any help appreciated.............Later.....................
I would put Lucas Oil Heavy-Duty SAE 85-140, would be good choice.
