Help, Advice, Owners' Discussion and DIY Tutorials devoted to the second generation C70, S40 and V50 Volvos -- awkwardly model year 2004 ½ onwards -- plus where to go for advice and discussion on Volvo's sporty C30 Coupe powered by Volvo's ubiquitous inline 5-cylinder power plant.
I had no idea that mine were shot... but upon inspection and trying to turn them while there was weight on the back tires, I could grab and move them very easily. So, anyway, I replaced them. I was going to install a new larger sway bar (that's still on hold for now) so bought some beefy rear end links. Wow, what a difficult job! There just isn't much room to work back there. I recommend a ratcheting spanner so you don't have to lift off of the nut and a long handled allen key. Took way longer than expected to do this replacement but I feel that the end links I installed are solid and very good. Very much a difference in how the rear feels grounded now. Over severe bumps the wheels don't end up plowing up into the wheel wells either like before. Here are the links I bought!
They are the Proforged 113-10146 Rear Sway Bar End Links. I bought them from Amazon but they are no longer available. If you google the part number various sellers on line sell them, some at a savings and free tax/shipping!
