Hey guys,
A while ago i checked what type rear axle ratio i had and if there was a sure grip in there or not.
I found a 4.10:1 ratio and seen both wheels spinning the same direction when rotating 1 by hand, trying to hold the other locks up both so i was convinced there is a sure grip in there.
Lately i've seen the car only pulling 1 tire mark though if i take off hard hard, if just a light wheel spin it still seems to spin both tires.
I wonder, was i mistaken or fooled thinking it has a sure grip or could that clutch be worn out, or is this normal?
Someone that has any idea?
I haven't had it open as yet, only changed oil once with an LS 90 gear oil and added 1 bottle of Mopar friction modifier.
It's a 489 3rd member, since the car was originally equipped with a 22" radiator (no a/c or axle package) it is not the original rear axle and i believe it must have came from a '70 Coronet 500 donor car. (must have been an option on the '70 500 as well i think?)
Future plan is to change the rear axle ratio to a 3.55, i am thinking if there is still any repair/service kits to rebuild those sure grips that will be a job for the same time.
