Selling my 1999 4x4 sr5. It currently has 99,500 original miles. I've had the entire rear axle replaced after the old seals went. Other items that have happened in the last six months (all paperwork is available):
front brakes changes
alignment
inspected at dealership (no problems)
replaced...
I had a slight warp in my tires that was causing vibration. Took it in to get an alignment and was told that my tires were slightly warped! Just means that the front right is getting worn a bit more than the others.
