2002 S60 Vibration Under Load

[HEKTIK]

Hello Volvo speed.

So a little back ground. Bought the car roughly 2 years ago with just a tad over 100k. Had my local Volvo mechanic(real good friend of my dads, only place he'll take his 87' 240) give it the once over and do a tune up. Plugs, Belts, Fluids, etc as this is my wives car and i wanted to make sure it was in top shape. fast forward about a year and we had to replace the ABS module. Now were having an issue with the suspension clunking and I found it to be the top spring seat on the passenger side. I'm handy enough with tools that I feel confident doing the work to the car myself. But here's our most recent issue. The car began to shake/quiver/vibrate when and only when accelerating. If my foot is not on the gas it rides smooth. I've tried to narrow it to a certain speed but it seems to do it at any speed. It's beginning to get gradually worse.

I searched around this and other forums and have heard replies any where from Axles(most common, and first place ill start) to coolant getting into the transmission.

Now I've gone on ipdusa and looked up the parts but not quite sure what all I need to purchase.

Could I get away with only getting the axles and seals or do I need the the axle bolts also?

Basically my question is, can some one give me a detailed list of what I need to purchase to change the axles?

And any links on write ups with torque specifications, etc. would also be great.

Any and all help will be appreciated. And thanks for having me on Volvospeed
