Torn drive shaft boot!

Just found out today that my front drive shaft boot is torn and its flinging grease all over the place. Just to give you a little backstory, I recently installed a RK 2.5" lift (stock mod) and put on some 33" tires, not a big deal right? Not overboard or anything, i stayed under 3" lift, tires are a modest 285 x 70 r17. I did that on purpose to try a avoid any issues with the driveshaft and everything thats prone to get messed up by going to big/high, what I really wanted was a 4.5 in lift with 37" tires... but I tried to stay sensible since it is a daily driver and I still got screwed :banghead:

Anyone else have this issue and have any recommendations? also at full droop, the front drive shaft is hitting the skid plate too.

Can you see that the CV boot is torn, or do you just see grease that flew out? I’ve seen a little bit of grease come out when a lift is installed, but it stops quickly if the boot isn’t ripped. If the boot is ripped then your angle must be too much, which shouldn’t happen with a 2.5” lift.

Do you have a manual transmission? Depending on your shocks some have seen rubbing on their skid plate and have to grind a notch in the plate to allow for extra clearance. Did you rip your slip joint boot too?

I have an automatic transmission and I did not actually see that the boot was torn but the mechanic at my dealership said it was. There is definitely some rubbing, but it just barely touches it at full droop. Wonder if there are extension brackets to lower the skid plate. Not sure about the slip joint boot, the mechanic never said anything about it. What he did say is that I could run 50 miles or 50,000 miles on the torn boot, he could tell me how long it would last. Also, he said he wouldnt touch it. That I needeed to take it to whoever put the lift on to get it taken care of. But thats me LOL so I guess I gotta take it to myseelf to fix :dance:

Did you use exhaust spacers? or check for clearance issues after the install?

RK, is known for giving people a much higher lift than advertised. Most of the times its not a problem when installed on a 4-door but I have seen 2.5" kits get over 4" of real world lift. Still, on a 4-door its not a big problem, if you have exhaust spacers.

Also, note RK's disclaimer at the bottom of their suspension pages...

****** For 2012 and newer models an aftermarket front driveshaft with 2" O.D. steel tubing is recommended, but not required.

Agree with this: Pretty common to need a DS for an RK 2.5" lift. I bought the RK 2.5" max travel and EVERY estimate I got said I would need a new front DS. I called RK and they agreed.

If it's damaged anyway, toss it and buy an aftermarket.

You definitely got more than 2.5" of lift from that RK lift. As others have said, they are known for giving much more lift than advertised. Heck most do. The Teraflex 2.5 coil lift I had was about 3.5" in front and 2.5" in the rear. I've heard many times that RK coils give even more. The pic shows that your DS was definitely at a critical angle. Time for a new shaft. :)

Tom Woods and Adams are good stuff.

I never measured the actual lift I got but I have the OEM bumper and there is really no added weight so I bet it did come out bigger but the angle of the driveshaft was exaggerated mostly because when I took the picture the jeep was on the rack at the dealership and in full droop. Ill take a pic in the morning of where the driveshaft sits with the jeep on all 4s.

Lemme ask a dumb question while we're on this subject. I'm looking at the RK 2.5 as well. When I heard people talk about replacing driveshafts I guess I always assumed they meant the rear shaft.

Are we saying its the front that may need replacing with this lift? Or both shafts?

Educate me on this.

Thanks

Front driveshaft (minimum) is on the way for me. Probably Adams since I haven't seen any bad reviews aside from packaging. After high-centering this weekend (resting on my skid plate in the pic, all 4 tires suspended- I think you can call it full droop) AND after reading this thread I crawled under Elivra this morning. Shew...driveshaft and boot OK for now.
A little surprised by the OPs problem only because it sounds like the Jeep is a DD. I was also under the impression that a 2.5 " lift, and maybe even 3", would be okay for at least awhile. Not in my case- prone to smashing things and all.
