I have a 99 sc f150 with a stock 4.2v6 auto tranny,3.31 rear ratio and 8.8 rear and 31 splines...i am runni gstock 235/70/16 tires..i just ordered an EZ locker for my two wheel drive..my question is..

1. what are the chances of breaking any parts like u joints, axles shafts, c clips if i do 90 percent of the time in highway driving..
2. i dont do rock crawling or heavy mud bogging...just light mud and gravels and sands..
3. dont want a limited slip coz my true trac cink out on me...the truetrac came loose with 4 bolts..( as of now the true trac has been fix by me using stronger grade 9 fasteners..)
4.would this set up last me a while if i regularly drove on pavement?? i dont beat on my rig....

 

Unless the remaining 10% is Baja racing -- practically zero.

 

thanks Y2K...actually the 10 percent is light mud and sand...will i be experiencing weird road handling on pavements??
