The right front seat in my 2000 Seirra has play in it. When you hit the brakes it moves slightly forward and then back when you hit the gas. I have inspected what bolts I can see and they all seem to be tight. Any ideas on what it could be or how to tighten??

 

Hi, I have a 98 2500 extendened cab... mine does the same thing. If the bolts are tight, the play is most likely in the seat track. I found mine that the track and rollers were worn causing the seat to "rock" when stopping and starting. See if you can find a good used seat tracks and replace them........good luck
