Hi everyone, my name is Sedrick. I am new to this forum. I just purchased my 2nd suburban, a 2001 LT 4x4. The rear wiper doesn't work. Has anyone replaced/repaired this issue? Is this an easy repair? I'd also like ti upgrade the brakes and suspension, any advice?? I also want to replace the tail lites and the upper rear corner posts. Will this come off easy ??
