Differentials?

Want to install Powertrax No-slip rear in my 2002 F150 2WD. My earlier posting( 'Powertrax', yes or no? ) got no responses. Limited slip is joke and is a waste of money. Any suggestions of other brands based on quality or am I OK with the Powertrax? Any suggestions or experiences would be appreciated. Thanks

Why is limited slip a joke?

my teacher from auto tech school goes to a lot of mud runs and races competitively. he has broken two powertrax lockers (no slip) then he spent a little more, put in a detroit locker and has had no problems. the powertrax is supposed to be more quiet than the detroit but does not appear to be as strong. detroit is tried and trued

(lockers go snap, crackel, pop when you go around corners, if you have a quiet truck the noise will be very evident)

Eaton's aren't cheap (eapecially for SCrew's: $1000 for the 9 3/4" rear axle) but tthey have a spotless rep also. The Auburn unit Ford uses has been broken by many F-150 enthusiasts, but just remember they don't call them enthusiasts for nothing. They go out and really push their hardware, and things break. The Auburn unit should be more than adequate for most anyone else though. I have never heard of anyone breaking an Eaton LS diff though.

The detroit is what I would use. It can't slip (if you get one wheel really stuck you can burn up the clutches as the engine turns past the holding power of the clutches, especially in a heavy truck), and still differentiates by allowing the faster wheel to unlock, and its very durable. However, you have to reset the rear, and its more expensive than other options. The Ford OE limited slip is fairly inexpensive. Its not the best, but if its mostly street driving where you don't want to blow away one wheel on a slippery turn, it should be just fine. I've heard of the powertrax breaking too. I think they are a little too complicated for what they do. You could try detroits gearless locker, its similar to a full blown detroit locker, but drops in place of the cross shaft and spider gears the same way a powertrax does. I don't know how durable it is besides its made by detroit.

Thanks for the replies guys. Much appreciated. Think I'll start looking at the Detroit lockers, they may be a bit noisier, but appear to be more reliable.
As far as the limited slip goes, $2000.00 having to replace every 35k miles and only apx 10% power delivery, no thanks!
