cranky1 My Durango has a Track Lock in it....I really don't care for the design of that type of LSD much. Bought the vehicle new and it started acting up (making noise) at 25k miles so I changed the oil in it and added the recommended limited slip additive and within 4k miles, it was making noise again only louder. Drained it out and cleaned out the crud again and this time added STP to the gear lube. Yup, you read that right. 40k miles later and it still works fine and is quiet.

S10xGN I added the "truck" version of the S-spring in my S-10 when I put new clutches in her 8.8", now she'll "chirp" around a tight corner if the pavement is good and hot. Hmmm, my '98 Dakota R/T does the same and it's never been apart.

Thats great info! Thankyou

dave350v8 [QUOTE=timothale;1620757]I wouldn't modify anything untill I had some miles on it under varying conditions. The old detroit lockers use to make noise when making sharp turns in a parking lot, just the way they were. Just be careful test driving it in the rain on smooth pavement until you know how it will handle.

Thanks will do, I wandering if its something I can sort out once Ive fitted it to my car,dont really want to remove axle again

dave350v8 Thanks for your input guys, apparently I might need to grind down the "springs" down a bit to help! Hopefully you are right and it should
be ok as it is!

gearheadslife because your cars weight might not be enough to cause the diff clutches to slip.. 2600 lb / 4 wider tires will help as the footprint will grip the road..
the wifes sporttrac is tail happy in the rear in the rain and the v6 isn't all that powerfull..

big gear head The Explorer rear end should have a Trac Lock differential, which is a clutch type limited slip differential. You shouldn't have any problems out of it.

Thanks in advance!
It won't happen unless you have welded spider gears or a spool- providing the diff isn't broken/defective.

123pugsy Well, you got my curiosity. Hopefully someone can shed some light on this.
