Recently I have noticed a vibration almost like a bottoming out, that feels like it’s coming from the back end, it’s only evident when going up a hill or under heavy load, and I’ve had the entire front end replaced last year, so back end makes sense.. Thanks for any help..

 

What kind of car do you have and how many miles?

 

Sorry, it's a 2001 Volvo S80 T6...with 175km

 

cv axles will do that. a way to confirm it is to make the vibration happen and go over a small hill to make the suspension go up. if you feel the vibration change with ur suspenison travel i would suspect ur axles. is it all wheel drive? I have seen it in alot of other cars hope this helps vibrations are no fun.
