CV Joint Leaking

I separated the halfshafts from the transaxle flange and noticed that while apart the CV joint(closest to the transaxle) leaked out some oil. Is it possible to disassemble and repack these joints? If so what grease should be used. The LH only leaked a few drops but the RH has created a mess. They were dry before I unbolted the axles. I searched previous threads and found that they should not leak, am hoping that this is not a major problem. Any advice would be appreciated.

SaskGT - Are you sure it is grease or might it be Transaxle fluid - which is all too common. A "leaking" CV joint is hard to imagine unless the metal cap has somehow become compromised. If it is transaxle fluid, there is a TSB to address this. In short, you remove the two bolts that attach the flange to the transaxle. Remove the thick washer. Now you will be able to see the end of the shaft coming from the transaxle and you can see and end-view of the splines on this shaft. The transaxle fluid likes to work its way along these flanges and drip into the coupler you disassembled. The "fix" is an easy one. Clean the thick washer real well using brake cleaner or similar. Then, spray some brake cleaner into a clean shop rag and clean - as best you can, the haft end inside the coupler. Finally, apply a nice 1/16" thick layer of Permatex Ultra Black to one side of the thick washer. Put that side against the shaft end and re-install the two bolts - and be sure to torque properly. Also be careful to torque the 6 outer coupler bolts correctly using both the proper torque AND the right sequence.

Hope this helps.

I actually pulled out the axle halfshafts. The transaxle is not leaking. The oil is coming out of the CV joint, it leaves a spot on the floor were it is sitting. The CV metal cap looks fine (no visible damage). It seems that once the bolts that hold the axle to the transaxle flange were removed it allowed some oil to escape.

I had the same problem,, cant see how you can replace the lost oil, just the left side, as well.

CV joints have grease not oil. As Kendall asked, are you sure it is dripping grease? Odd, because grease doesn't like to drip.

It would appear that the grease has separated to some degree and the lighter portion is leaking out. If these joints can not be easily taken apart I will probably hope that this change is not too important and reassemble.

If it is leaking why not replace the part?

They aren't that expensive and a failure can be dangerous and cause a much more costly repair.

Ultrasportracing, I also tried and got the same result. It would be a very good price. Did you use the axle that had leaked some?

Yes , was definitely oil that leaked out, and between the 2 mating faces of the CV joint, with no transaxle in site, oil was cleaned up and a few drops appeared latter, now Done about 200 miles since assembly, but will keep an eye on it, if it starts to wear prematurely then one would expect to feel a more aggressive clunk when taking off.. Did you check to see if it was actually oil or watery grease..

Yes I used the axle,, After opening the outer joint, cant see how what I saw leaking was actually from the CV joint,, as the type of grease is completely different from what I saw leaking out, although a small amount and didn't reoccur once cleaned up. Can only assume that the oil was from somewhere else, or part of an assembly process. When my C/v leaked it was on the workshop floor ,nowhere near the transaxle. Car has done about 300miles now and no sign of any problems..

It's an easy fix I performed on my own.

Dragan at Autonation in Mobile replaced the right CV joint, but the kit also has the left so I have those parts too.
He replaced the axle bolts again too.
Cost $2400.
