I own a 2006 Equinox, All Wheel Drive. The recommendation tire size is P235/60 R17. We bought it used in 2015, and it came with P235/55 R17. For the past 3 years, I have replaced 2 driver side wheel bearings and 3 passenger side wheel bearings. I have gotten 2 new front tires, 2 new front struts, and a front end alignment. This has not resolved the wheel bearing issue. Is having the incorrect tire size the culprit?
I really doubt going from a 60 to a 55 aspect ration would do that. If the rims are aftermarket they might have the wrong offset. As far as the hearings, are you using OEM?
Reminder: with AWD all four tires must be identical, with identical wear, therefore require rotation each oil change.
I know someone who has done 12 wheel bearings on theirs. I have only done 1 wheel twice on our group.
No, but aftermarket rims could be if you have those.
The hub bolt was probably over torqued by some lazy mechanic using air tools instead of a torque wrench.Improper installation is the #1 cause of failing bearings.
If the wheels move the center of the tire outward from the designed location to the hub bearing the bearing will be significantly stressed.
I thought the same, however, I have used two different mechanics. The first one I have been going to for 20 years, the second one, a friend of mine that has owned his own shop for over 20 years. In all honesty, I do not think incorrect torque is the issue here, based on the number of bearings, and the use of two highly reputable mechanics.
