01 Yukon shakes/vibrates at highway speed

It's most likely not a balance issue if it did it with other tires before AND he just had a balance AND alignment....geesh, people. Read the whole post.

I'd follow WoldD90's advice and check everything. If you don't know how, take it in to a mechanic and ask for an estimate. They will tell you what's wrong with it, then you can decide how to go about fixing it. Estimates are generally free.

knowing the problems with our rides it usually turns out to be idler arm and pitman arm issues but... down downplay the negative effects of too much tire pressure. I went to get my oil changed the other day and forgot to tell the morons there NOT to mess with the air pressure in the tires and the idiots pumped them up to what it says on the side of the tire which says like 36 psi, and of course when i get home and checked them because it felt like a buckboard wagon(shaking and all), they read 38 psi each tire. Dropped them down to 30 psi and it rides like a caddy again.

Went to replace brake pads today and found a sever issue. Whoever pulled the calipers last time cross threaded a bolt that holds the caliper to the mount. End result was that the caliper was at an angle on the rotor. it made my pads look horrible and not to mention made them wear ridiculously uneven. going to finish taping the threads on this side and check the others for the same problem. maybe this will fix the vibration. just keeping updated I guess.
