Q&A

I am referring to the Control Arm Bushings. My Volvo shop is suggesting replacing my transmission and 2 axles, and control arm bushings, not my wheel bearing set/hub in front.

It seems like a lot of service. What can I ask to be sure I am not getting more service than actually needed. What is your recommendations? What do I need to get repaired/replaced out of all three. I drive about 30 miles per day at most.

Another shop (not dealership) is suggesting replacing the inner CV joint. This seems more reasonable. Should I start here.

Without driving your car and inspecting it, it's hard to know what might be going on here, but the approach of the one shop to replace the transmission, axles and bushings is crazy.
The other shop that is recommending the inner CV joint is the person I would have look at this. They seem like they are trying to fix the car and not rip you off.
The inner CV joint will cause a vibration at different times, and it may very well be your problem. I don't know that the inner CV Joint is replaceable, you may have to replace the entire axle (my co-worker just had the same issue on his S80, it was the left axle and it vibrated at 60mph)
Good Luck, let me know how it turns out,

Thank you for sharing your knowledge. I did get my right axle replaced at the shop that actually wants to fix my car. The vibration is gone. That said, my Volvo is at 96,000 miles and has other issues as well. I am just now starting to get the knocking sound...time to replace bushings.
