W124 Rear Knuckle Part Sourcing?
 

1994 E420

I had a mild disaster on the road to work. The right rear axle failed taking out the wheel bearing and a few other bits and pieces. At this point I need to replace the axle and the knuckle assembly but I'm not sure where to look. I sent Potomac German an email but any other suggestions?

Did the actual knuckle (wheel carrier) get damaged or just the wheel bearing itself? The wheel bearings should be available seperate, just need access to a press or, the right tool to do it on the car(about $600). If the wheel carrier is in good shape, i dont see a reason to replace it, other than to get the whole thing all together and assembled.

My mechanic suggested I could save some time and money by getting the carrier as opposed to pressing in a new wheel bearing. Your right though, I haven't done my due diligence yet and examined the knuckle yet. From calling around it may be more practical to simply get the bearing.

wheel carrier incl bearing ran about $800 2 years ago. I had an indy replace the bearing on car for about the same, which was a helluva lot less than the Wilmington,DE dealer wanted.
The most cost effective way for a DIYer is to remove the carrier and then bring it to a machine shop to get the bearing changed, but your car is OOS, and you do a lot of work yourself. Plus, your rear wheel may need an alignment afterwards.

If you do remove the carrier and take it in for a new bearing (bearing is about $60 IIRC) also have the lower bearing/bushing on the carrier replaced, cheap and a common failure item.

I've got a right side carrier w/bearing from a 1988 300E you can have for a very reasonable price. Bearing is 10K miles old (replaced in 2006). BUT, knowing Daimler Benz, it is most likely different from the one in your V8.:(

I had to replace that knuckle on my '91 4matic wagon, they said it was different than the 300E and the same as a 400E, replaced it with a used 400E knuckle.

I don't know if this is useful, it was an Indy that I trusted and knew well.
