Front drive shaft after lifting the JK 4"

So, it appears that my front drive shaft and my transmission have been fighting. I assume this means I need a new aftermarket front drive shaft that is thinner so it won't rub. At least that's on another forum, but I prefer to run it by the awesomeness here first. Thoughts on what to get or do?

TIA!

So its just rubbing on that lip and bent it a little? Looks like its already self clearanced to me and i wouldnt worry about it. maybe pound the lip a little flatter with a hammer

It was a Jeep thing, but all that stuff broke

Thanks. The boot is also torn though. Will the joint (u-bolt or whatever) wear out now?

Maybe one of the JK guys will chime in who know but I assume that under the boot is just the splines that slip in and out. On mine those are already exposed and I don't have issues so I wouldn't think it's a big deal.

I will examine further and report back if I can get some better pictures.

Must be a 4 door. I don't think those drive lines have splines that slip. Their more like a cv type, I'd have one built before doing much serious wheeling. As for the clearance I've installed lifts on a couple we had drive lines built then trimmed the cross member for clearance.

ITS ALL FUN AND GAMES TILL SOMEONE GETS HURT..... THEN ITS HILARIOUS!!!

Yes, it's a 4-door. "Have one built"? Like from 6 States?

Yes, we've done a couple and they have both needed different length shafts. Jason at six states in Orem does great work.

This is a common problem for 4 door JK's lifted 4" and up. Yes the stock drive shaft has a CV joint under that boot. If the tear is bad enough to let dirt/water into the joint it will eventually fail. No grease = eventual failure. Unfortunately the boot cannot be replaced. You will be OK for a bit but keep a close eye on it. For peace of mind I would replace it. At 4" of lift you will eventually need to get a new aftermarket front driveshaft anyway. Sucks.

Thanks for the info guys. Maybe I can put a new on one when I replace my front diff.

Price out Gaylon's in American Fork before committing to Six States. 6S wanted $75 to start for shortening my front shaft. Gaylon's did it for $55. Plus they painted it for me.

Yup, Gaylons did an awesome job shortening my front drive shaft. got it back all painted and he gave me an extra set of straps to keep in my rig.

Oh, there probably is. But I don't like crossing Point of the Mountain unless I have to...
