This is gonna be long winded but I can't take it anymore so I decided to reach out to you guys about this. I have a 2005 XC90, about 170,000 miles AWD 2.5t. For a while I have had slight vibration issues while driving the car, mainly at highway speeds. I replaced the front struts/springs and it seemed to fix the excessive vibration I had in the steering wheel, but still had some residual that I chocked up to the tires being out of whack due to the past springs.




It started to bother me but for the past few months I have had to take longer trips, ie 6 hour drives and its really become exhausting. A few months ago right before a long trip I had a tire blow, but I got some used tires instead of new since they were readily available and I had to leave that day. The vibration seemed worse with those, and really the front ended up feeling really squirley after driving it for another month. I figured something is for sure not right up front, took it in, and they found that the front bushings were shot. So got those replaced, and I had the shop look at it, and they said all seems fine besides my tires. So I bought new tires, installed them (and honestly I waited to buy the new ones cause I wanted the suspension fixed so I didn't blow through another set of tires) I got the tires installed, and low and behold I still feel a slight vibration. I took the mechanic on a drive and he said its normal, and I wanted to punch him in the face, literally. I told him my concern is that this is minor now, but as time progresses it tends to get worse and worse which is making me believe it is warping the tires, and I don't want to keep buying new tires. I asked if it is possibly the bearing, but he told me that it would be constantly making noise, which I do I have some kind of slight noise during acceleration (that I would say was similar to an issue I had with a Maxima when the axel needed to be replaced, but much quieter), but he says its not it. I asked a Volvo Specialist shop as well and he said it maybe the front engine mount but I don't understand how that would effect the tires, and it would be the same regardless of what kind of road I'm on, and currently that is not the case. Some highways its more pronounced then other highways.


Now to describe the vibration, it is a very fast vibration, pronounced a little more around 65, which I would guess is because my wife normally drives on freeways at that speed and its been effecting the tires already (about 1000 miles on new tires). When I get up to 80 its still there, and just faster vibration. I can see the passenger seat shaking a lot, and the back seats shake a lot (could it be rear shocks? I have not replaced those yet). I do also have aftermarket 18 inch rims that are chrome, and I have literally driven at highway speeds next to the xc90, and it appears the right rear almost has a slight wobble when at speed and looking at the chrome reflection vs the other rims, but again could this be a shock blown?


I'm sorry I'm a bit all over the place with this, but I just got back from a 11 hour drive and I am at my wits end. I feel like my body has been placed into a home depot paint mixer, and this is making me want to sell the car. I need to figure out what it is, or more components are going to keep failing. I've already spent a lot of money trying to resolve this and I have to this date, no solution on it. Please help, and I'll be happy to answer any questions you guys may have. Thank you in advance!
