I have a "99" Suburban and was recently rear ended. There was no apparent damage to the other smaller vehicle but enough damage to my vehicle that the rear bumper is being replaced. My question is, could this also have caused damage to the drive train? I.E. transmission, 4 wheel drive etc. and should this also be covered by the insurance and how would I go about it? I'm thinking any problems I'm having could also be attributed to the age of the car,but I'm noticeing things now that I did'nt notice before.
