Chevy & GMC Vans

anyone done this? Is it difficult?

My slider on the 87 rattles and I believe that the rollers are wearing down.

No it isn`t. if you mean the lower rollers. just a few bolts in the sliding door. and disconnect the cable.
just put a piece of wood under the sliding door. it`s heavy...

the upper roller. just onbolt it and replace.

when you replace the middle rollers. thats a lot more work.
remove the inner pannel to get to the little bolts that connects the sliding door metal sheet.
remove taillight to get the last bolt out.
replace it and ready you are..

thanks!

can anyone shed a little more detail on this operation. like where to get the rollers and such?
