Mopar Manual Transmission Fluid, Part # 4874464, List price per Quart is around $20, dealer is free to set price, may be lower. Only way to accurately verify wear pattern is with gear marking compound. With allot of backlash, may be due for an overhaul.

well i wouldnt dought it. some one had been in there doing god knows what. i found one of the trust washers for a spider gear just laying in the bottom of the rearend. so i pulled the cross pin and put it back behind the one spider gear. now am i right on the 9.25 rearend doesn't have the shims to center the carrier. i just need to pull the bearing caps and there is a adjuster style sleave. i just need to back one off and set the other in more. i've done work on rearends befor but im no pro at it. i may just take it down to a local shop and have it looked at when it getts warmer out.
