Yes, it depends on one's mechanical ability, how much time one has and also if you have another car available. I was taking my time in doing this job as I had never done this before. I have not worked on any model besides the 124 chassis.
Rear Hub removal is easy by disconnecting all the links.
Then, in my case the joint/bushing in the rear hub was bad
so, while the fellow was pressing out the hub and the bearing
I also had them press out the bushing.
If these are bad, then generally other rubber bushings need to be closely looked at. My differential bushings were cracked, so replaced those.
