Vibration

Hello, 2004 V70R, 150,000ish miles. Ive been getting a pretty bad vibration at highway speed but only with throttle applied or cruise control on, the second I let the car just coast the vibration stops completely. I recently posted this question on facebook and the immediate response was bad half shaft somewhere. I checked today and didnt find any play in the front half shafts, but both the rear shafts have quite a bit of lateral in and out movement. Can anyone tell me if there is an appropriate amount of movement in the rear shafts or does it sound like both rears need replaced? Thank you!

Vibration under load only is a classic symptom of a bad inner CV joint in one or both of front axles.

That's been my experience with vibrations under load - front CV axles, as VTL stated.

Typically you can feel if it's front/rear biased though. It's the left to right that always throws me off. When my drivers side CV axle is bad I feel it on the passenger front. I'm sure the rears go eventually, but I'm at 283k on our 04 XC70 & I've replaced both front CV axles but the rears have never been touched. I did the fronts between 226-228k miles, for reference sake.

Has your VR been beat?

Hasnt been beat on too bad to my knowledge, im the second owner, first owner barely touched it for the first 5 years of its life according to car fax. Ive had it almost 2 years now, ive had some fun in it but no hard launching, or anything like that. I have put lots of miles on it on less than ideal road surfaces though.

I’d take good care of it & drive it like you plan on keeping it for the next 10 years.

Start shopping, try to get GKN/Lobro CV axles if you can (if you decide to do CV axles). I’d avoid any lesser variant.

A few years back AutohausAZ had the best prices I could find on them. Not sure if that’s still true though.

Autohaus is over twice the price of IPD, I dont think IPD has a history of selling garbage, can anyone confirm that the IPD CV axles are only half as good as the autohaus ones?

Don't think it's GKN/Loebro. GKN is/was OE for P2 Volvos, it is about twice cheaper than new Volvo axle, so around $300. They do last, unlike these cheap Chinese axles.

I've had bad experience with all new aftermarket axles in price range up to $180/piece. GKN works fine.
