Spoke with Quinn (All J) today to inquire about my CV vibes (post FrankenLift). He basically said everything I've been reading. Wait for the frontend to settle, ram it into a culvert, don't baby her, etc. He said the cold weather (DC/VA) might result in a longer break-in period. He also stated something interesting, he said that he's come accross a couple of KJ's that came from the factory with bone dry CV joints. He said that might be contributing to my CV vibes. He recommended squeezing the CV boot to see if grease came out. What if grease doesn't come out? How do you pack them with grease? There's no fitting. I suppose you would have to remove the axle, repack the joints and crimp the boot back in place. Would you swap sides for even wear? My boots aren't damaged and I didn't experience any vibes before but it got me thinking. When should you service the joints? The steep angles might be aggrevating the situation. Would you be better off replacing them with new units? Is this a do it yourselfer or a $200-$400 dollar job (+ parts)?

Maybe get one of those greese injection syringes and pump it full of greese. And if you are worried about the hole then I guess touch it up with a bit of RTV. I have hear of other people doing similar things, just never on a KJ before.

Syringe sounds easy... think it'll work? Know any heroin addicts? Will grease flow through a syringe? Maybe a turkey baster (lol)? I was thinking of maybe removing the crimps and boot, smearing copious amounts of grease on and around the joint and replacing the boot. I think you can rent a tool to re-crimp the boot back in place. I'll probably mess the whole thing up.

They do sell syringes spefically for grease guns. I believe they are called grease needles. Should be able to go into any autopart store and pick one up.

Here is a set at harbor freight

Grease needles... they look nifty. Thanks. That would make things alot easier.

making a hole in the boot and putting grease in there wont do nothing. the axle has to come out and taken apart and the grease has to be packed in the ujoints.

^its cv joints, not u joints. It doesnt really work like a bearing would, putting grease in the boot can help the joint. The cv joint is kind of like a ball and socket, and the ball has ballbearing in it to move it around in the socket. They are really cool to see taken apart i think, alot of engineering in them.

edit: ive got one of those needles, i would be afraid it would let sand in though? Ill just take my lift off and use the 7yr/70k warranty if they ever go bad.

Like somebody else mentioned...I would just clean the area around where the needle went in and dab some RTV silicone sealant on it...It should hold well and prevent anything from getting in.

I'd re think pokin a hole in your CV boot. From what I've been told the start of the faliures can be a torn boot. I'd check with someone that REALLY knew what they were talking about before doing that (suspension specialist..ect...).

I've you've got dry boots take it up with the dealer 1st ...?

Swap the dry ones for new ones ?

The only time you have to repack your cv joints is when the boot rips and all of the grease comes flying out. Its a sealed unit. They aren't really designed to be serviceable. I think someone already mentioned this but the needles are for u-joints. Two different things. You never had this problem until after the lift. That tells me its someting with lift. Wait for it to settle, double check everything over again and go from there.

I've hear of people actually using the grease needle to lube their sealed ball joints on the Dakota's and Durango's to make them last longer.
