I'm seeing conflicting information online about this...

My 343k-mile boat needs new wheel bearings out back. I could pay a shop $600 to do them, or I could grab some full knuckle assemblies for $300 tops and swap them myself.

Thing is, these are getting hard to find. I know the SC430 front end bits are quite interchangeable as I've used the control arms a few times. But what about the rear? Will a complete knuckle/hub/spindle thingy swap right over?

 

Haven't done so myself, but from what I heard, yes

 

They really isn’t any parts that could be worn out on your car that u want to install used parts. You can certainly get new hubs for your vehicle, there are some bushings and knuckles that also wear out and also a couple ball joints, you probably need all of them with 343k. There is also some bushings on the rear diff that wear out/ u need to do a good inspection and start fixing the problems u find

 

Yeah it does need a lot but I can only justify spending so much money on a car this old. I've got a line on a salvage yard SC430 with only 35k miles on it and would have zero hesitations about bolting in those knuckles. Save a ton of money and will last 98% as long as a brand new part.
