In theory this would lead to longer axle life because you'd end up using both directional surfaces rather than just one. Of course swapping does nothing to aleviate the wear on the balls in the joint but they are pretty tough. This wear issue is what makes rebuilt axles so undependable, usually the axle core is inspected and measured, if it's in spec they just clean, re-lube, and reboot it. If it's out of spec they regrind the chase and the spider to the next larger size ball, then clean, re-ball, re-lube, and re-boot. The problem is that when the CV joint was originally manufactured the wear surfaces of the chase and the spider are hardened as are the balls, they don't harden the reground surfaces and the axles don't last nearly as long as a result. Now when you combine that functional flaw with Chinese/Mexican/who knows what third world quality control remanufactured axles have become a disposable wear item rather than what was originally a part that might last the life, in the Benz case, long life of the vehicle. |

They wear into the other side of the CV joint as they will be rotating the opposite direction.

Thanks guys, that makes sense, but I wouldn't have thought of it! I'll be sure to swap them.

I would not swap them side to side.
many many many bearing manufacturers specifically state not to swap wheel bearings from one side to the other due to the bearings wearing specific to the race. the cv joint would be the same. it's turned one direction for hundreds of thousands of miles, the grooves are mated to the wear patterns in the balls, the oil keeps everything lubed correctly, and the cleaning and re lubing gets any wear material that's developed over the years out. I vote to keep them on the original side.

They'll be wearing against an almost virgin surface on the opposite side. It's an old VW trick, when the CV joints wear out we could swap them and get lots more use out of them.

I posed this in another thread, but realized it really belongs in this one, especially in case anyone searching wants to follow the progress of this project:
The good news is, I got everything off and started to drop the subframe ... but, the back half won't drop. The bolts are all out, of course, but when I go to lower it, just the front lowers and hangs from the back. I tried gently coaxing the back mounts off the frame with a prybar, but didn't really want to go to town on it and damage something. Is there something I'm missing here? I don't think it's hung up on anything. Are the bushing sleeves just stuck to the frame posts maybe? If so, should I try torching them, or keep prying? I'm trying to be careful because I don't want it to suddenly pop free and crash down. Obviously I have the jack under it (plus an extra scissor jack) but still don't want any sudden lurches. Help?

I don't envy you. I spent a good deal of time beating on the one in my parts car, finally cut it out. The subframe still has the mounts in it, ... I soaked and pounded for a while until I lost interest, even tried a ball-joint press.

That's not too encouraging! Hopefully I'll have a bit more luck. I don't need to get the mounts out of the frame, since a "new" frame with new mounts is going on. But I can't cut the mount that's fixed to the car ... I'm gonna need that! I might try sticking the ball joint press I have in there ... it's about the right size.

These are not going to come off. For anything. I am never going to finish this stupid project. Should I try firing the torch up bthe bottom of the mounts? I am prying with a huge prybar, and have also tried a chisel and a wood splitter with a big hammer. They don't break because the rubber gives and can't possibly exert enough force. And I can't seem to get anything onto the metal part of the bushing to avoid that.

That's where I decided to cut the thing out of my parts car, ... so I can't help you there.
I'd be starting to consider pouring a low durometer urethane into the bushing and leaving it there.

My big fear at this point is that I'm going to damage the post itself. Then I'm really, really up the creek. I guess you could weld one back on, but that sounds like it would be pretty unsafe. So I want to be careful not to damage the post or the threads.
