Hi, my 2001 s40 (80,000 miles) had developed a vibration problem. When I drive at 40-50 mph the front vibrates/shakes. Sometimes this occurs at
30mph. I got the tires balance, that didn't fix the problem. Took it to the volvo dealer, they said:- the front left/right drive axle shafts are worn and needs to be replaced (cost $1500)(wow) due to play in the axle. took it to pep boys and after their inspection the mechanic said that the axles seem fine, maybe its a transmission problem, they can rebuild
both axle sides for under $400. So I am not sure if it is a drive shaft or transmission problem. Should I get a third opinion? Thanks in advance
