Lift the body
Will a transfer case from a 91 Chevy silverrodo fit a 2001 Chevy suburban?
This would not be a direct swap.......adapters and computer change is inevitable!
Got to lmctruck.com they have every part for a 73 - 91 suburban you can think of. Their catalog online shows explode views of all kinds of things and numbers all the parts so you can buy the ones you need!
No it will not interchange.
Check the brake light switch. It is defective or out of adjustment.

subtract 1919 from 2010 91 If you have a computer your computer has a calculator you can use that
