Another Torn Boot on Front Axle CV Joint

[Aj58]

24 Mojave X 15K miles.

It looks like there been 3 of these in the past month on this forum. Of course, not a ton and we always hear the worst here but none the less interesting in that they are all low mileage.

24 Mojave X -10K miles
25 Rubi - No mileage mentioned
21 Mojave - 7K Miles
24 Mojave - 22K Miles
24 Willys - No Mileage Mentioned (JL)


On top of this, its a general backorder? Is there even a part number for the oem boot? Or is it the entire axle rod swap out.

If this is deemed not under warranty are there any good replacements that are not OEM out there? Replacement price is no joke.

Also curious if any of these instances were covered under warranty? Feels like in everyone's story is it was not covered. Its pretty obvious if you look under my truck that I don't wheel. This feels like a manufacturing defect on the boot.

Curious if anyone has any updates if they got it fixed yet.

Going with RCV axles is one solution, albeit a bit expensive, or you could pick up a generic replacement CV boot of appropriate size and install that until a proper OEM part comes available.

I like the RCV’s in my JK. I don’t like the clicking when the cage has some wear. I’ve rebuilt them once and the clicking in 4x4 when turning is back. I just live with it. Explaining why your expensive axles are doing that shouldn’t have to happen.

fair point,
honestly It looks like I’ve lost a fair amount of grease and have been in the beach with it so there is a nice mixture of sand and grease. I’m hoping they replace the joint but if not it’s still over 500 in parts for one. Sure it’s unlikely it will happen again hit it just leaves a bad taste I guess.

In which case it'll be necessary to disassemble, clean, and regrease the joint in addition to replacing the boot. As far as what I'm seeing, the OEM CV style shaft only comes as a complete assembly, you cannot get just the boot or just the joint.

What it comes down to is you need to answer the following questions: what's the likelihood that they are going to replace the shaft under warranty, what are your wants in regards to keeping things factory versus upgrade/serviceable parts, how much time and effort are you willing to put into repairs, what's your tolerance level for risk for further damage, and how long are you willing to have the vehicle out of service. Answering those will help determine whether the best path is to go with RCV shafts, keep driving it as is and hope the joint doesn't fail before a new shaft comes available, replace the boot as a temp repair until a complete factory shaft can be swapped in, replace the boot as a permanent repair, or swap in a u-joint style outer shaft until the proper one can be obtained with the knowledge that you can't/shouldn't use 4auto mode.
