    They were used on quite a few 2wd versions of Vans, Blazers and Suburbans, in the late 80's early 90's. But I was told those version aren't forged. Cast aluminum instead.

    What have you done to your square lately??

    I used a cloth wheel(s) from harbor freight on a battery drill with green rouge, followed by a wheel with white rouge, followed by a wheel with Mother's Aluminum wheel cleaner. But first i used a 2" wire wheel on the drill to remove the oxidation, then sanded with a random orbital with 80 grit...

    '83 305 No more ESC, but now it is dieseling

    So I think may have resolved my desiesling issue. No dieseling currently after refilling with 93octane and pouring some Seafoam down the carb while keeping it running, then put the rest of the bottle in the gas tank. I bought a timing light to check the timing, I cannot find a place to stand...

    '83 305 No more ESC, but now it is dieseling

    I was having intermittent trouble with my truck starting when warmed up, and diagnosed it as a bad ESC. I could bypass the ESC it would start, hook it back up would not start, bypass it again and it would start. I got another ESC module and now the truck will always start, but it runs badly...

    Bed mat for SWB Square???

    I’m having trouble finding anyone that sells a custom fit rubber bed mat for my SWB? Does anyone still offer one? I don’t want some hacked up looking “cut to fit” mat.

    Weird reverse light problem

    Fixed. Something to do with the trailer lights. Unplugged the trailer adapter harness from the truck, problem went away. I was originally thinking it was a switch in the column or something, this thread saved me a LOT of time. Thank you!!!!!

    Weird reverse light problem

    If it was shorted this way wouldn’t all the running light come on when in reverse too???

    Weird reverse light problem

    First time poster. I am having an issue with my 1983 Sierra Classic. The reverse lights work normally when the headlights are off, but they stay on anytime the headlights are on? Any idea where to start troubleshooting.
