I have 6" Fabtech and 3 inch body with 38's. My drivers side inner CV boot ripped about 6 weeks ago. I replaced the entire shaft with a NAPA one. Yesterday....Grease everywhere and a huge gash in the new inner boot AGAIN!!! ARGH.. There has to be a stronger boot or better angled shaft somewhere? Please help cause it is way to much of a pain in the BUTT to keep changing shafts every two months.

 

I'm not sure what would be causing them to tear but it isn't the angle on the cv axle. The Fabtech lift achieves the lift and still obtains the original cv angles by dropping down the front differential and cross member in alignment with the new lift spindles. The only angle that changes is the front drive line and rear drive line. Something has to be causing the tear..... but it's not the lift. Unless you have your T bars cranked all the way, the angle should still be the same as factory or very close. Just my thoughts.

 

when those things tear grease shoots EVERYWHERE!......as im sure you know....no clue what could be causing that other than if you have a leveling kit or your t-bars are maxxed out
