trak-lok 9" rear
my 79 f-150 4x4 rear axle tag reads 3L50 and i'm assuming it has a limited slip differential. do the clutch plates in these axles have to be replaced to make it grip better and where's a good place to look for replacments. i had one in another truck i used to own and it work well, thanks.

Yup, those clutch plates do wear out. Any of your local shops could put in new ones, but I'd advise pulling the pumpkin yourself to save change.
If your knuckles ain't bleeding you did something wrong.

Make sure when ever you change the fluid that you remember to put in the friction modifier, usually about 4 ounces. Clutch type diffs do need this to help the plates grab for correct operation.

I just rebuilt mine, cost about $600 by the time I was done changing axles and what not (460's are kinda hard on those 
) Make sure you have an extra "steel" put in. This will increase the breakaway force of the posi. I'm not impressed with how easily the posi will disengage. I didn't do the extra steel like I should have.
just my $.02

[font size="1" color="#FF0000"]LAST EDITED ON 19-Jan-01 AT 11:00 AM (EST)[/font][p]thanks to everyone for the info. the extra steel shim you put in the clutch pack sounds like a good idea. i'm gonna try that. thanks again.
