Is time to change my axle oil. I have a canadian 12 bolt posi. How much oil I have ti put ? and it is better synt oil ? Can I put gm limited slip additive it is the same as the gm posi additive ? Thanks
posi lube drain well. then put in posi lube additive and then fill untill the lube begins to run back out of the filler hole. replace the plug, works every time:laugh:
posi lube Yes, that should be the same additive. It is a must have otherwise the unit will chatter untill it self destructs.
i would suggest that u buy the posi lubes/additives from a gm dealer . all lubes are not the same . i have a friend (67 el camino) who has tried the non-gm posi lubes & has had nothing but trouble & had to switch back to gm fluids .
