OEM Mercedes Rear CV Axle.
We remove the old boots, clean and test the joints and install with new boots. We are now exclusively using Astoria 2000 brand CV boots to rebuild them. They are very high quality rubber--nearly the same thickness as OE boots--that is more elastic and thus less prone to cracking than the OE boots, especially in cold weather.
These OE German Mercedes axles are much better in quality than all the made in India or China remanufactured axles, but can fail prematurely if the boots rip open and leak oil, drying out the joints.

This is the "can-style" axle that attaches to the differential with a c-clip, not the more rare bolt-on style. Check yours for compatibility.

If you would like to send your axles in to be rebuilt: To avoid shipping us cores that are not serviceable, please inspect your axles thoroughly. Joints should be stiff, not loose from side to side, or with any metal grinding. If they click or crunch while driving, they are not rebuildable.

Fits W116 Chassis US, W116 Chassis Euro, W126 Sedan Gen. 1, W126 Sedan Gen. 2
