Update:

Posi doesn't work in 1st gear but all other gears.

Ill be doing a rear swap at some point as well, where are you located?


Try cutting the wheel and see if it will lock one way or the other, mine seems to like to grab turning left and not right, also, I know with mine, it has the tendency to just blister one tire if you just smash the throttle, if I ease into it and try to hook it will lock up both tires.

Food for thought, I picked up a low mileage 3.42 rear out of an ls1 car to swap in, you can find them for pretty cheap if you keep looking, could be a crap shoot for the posi but, but for me the the cost of gears and a new posi alone made buying a whole slightly used one much cheaper and given this one has lasted 175k, im not overly worried about killing another lol. Have to swap axles and brake backing plates but nothing crazy hard.

Ask pizza I broke a stock ten bolt on a iron headed lt1 impala SS motor at track with a eaton posi hance (3,0000 dump it )with4:10
Ben there split diff in two and snap pion shaft in 1/2
So if daily driver swap used rear in ad hole unit save for upgrade
I now have moser 9" with a wave lock diff with 36 spline axels a life yes life time warranty, most only have a year
Only thing is wave lock cost I paid two years a go 800 I think but now ther like 1200$

Yeah its my DD.

I plan on taking it off the road for the winter and upgrading the brakes, suspension, and now the rear end

because the clutches are to weak to hold the torque

Well I know squat about axles so what should I replace?

Posi should be rebuilt or replaced. Cheaper to get another rear out of another f body

Well come winter time I will do some searching. Thanks

Just either buy a good one or go on Craigslist. I've seen 10 bolts for 200 bucks everywhere
