    Center/carrier bearing orientation - 76 C20 suburban

    WOW, that doesn't look familiar. I haven't had to service this on my Crew Cab so not sure if it is different style on the OBS trucks.

    What would you pay for this truck?

    I didn't know they ran the chrome early style dog dish hubcaps through '77. The dealership took Dad's 75 Sierra Classic to a shop off-site to add the extra tank, and they did a hack job on it. From what I've read and heard, that's unfortunately commonplace.

    Agreed on the longer WB making it ride better. One of many reasons we preferred longbed trucks. I had a buddy in high school that took me out wheeling in his '74 Blazer K5. Fun,and we were just going around the bayous and where subdivisions were going in near school, but the short WB made it not...

    Unlock barn doors from inside

    All I remember the '90 having (only square Burb we had with barn doors) was the tab on the bottom of the left door, to open it/release the striker, once the right door was open. And we opened the right door with the key, unless someone opened one of the front doors first and hit the power locks.

    Maybe they don't have kids yet....at lunch we saw two families, probably the kids are cousins, six between the couples and another on the way. One of these skinny girls that looks like she ate a watermelon when she is pregnant....

    My brother has a theory about this very thing. He noticed many of his smaller female friends had Jeeps or trucks, because they felt safer and could see further ahead in traffic. Might be a reverse macho thing too.

    Center/carrier bearing orientation - 76 C20 suburban

    It looked like a metal jar lid IIRC....both Burbs are long gone so IDK what exactly it looks like, or have measurements.

    1977 C20 Heavy duty with 11.15 drums?

    I think the later style OBS has slip on drums. Pretty sure my '97 does because the shop didn't charge for pulling the axles and refilling the diff oil when they changed the wheel cylinders last fall. But some of our guys on the OBS/400 forum with older one tons have the square body style drums...

    What have you done to your square lately??

    Yup, tolex is a fabric that Fender and other makers used to cover amplifier and guitar cases. Has a nice pattern and it's pretty durable.

    1977 C20 Heavy duty with 11.15 drums?

    I can vouch that on my OBS one ton with 13" brakes on a 14B FF and 16" factory steelies, the space is a bit tight....as in the upper picture @AuroraGirl posted. Just enough room to get a wheel retaining strap between the wheel rim and drum. Yes you can put this big of a truck on a flatbed...

    Center/carrier bearing orientation - 76 C20 suburban

    The way I remember the carrier bearing being on the '84 and the '90 Burbs, the dust cover was a metal part that threads onto the external threads on the driveshaft. The zerk/grease fitting is on that shaft, and that was something I hit every grease job.

    1977 C20 Heavy duty with 11.15 drums?

    That drum does seem a bit small....my one ton has that rear axle but hydro boost instead of vacuum booster, and mine definitely has the 13" drums. Got a full floater out of a one ton square body in the shop, and I'm 99% sure it has the 13" too.

    New to the page

    Yup my Dad woulda loved your two tone brown and cream 3+3, he always wanted one and that's the color combo our 77 and 79 Burbs were. He's probably looking down at me and shaking his head, seeing me and Mom with the OBS CCLB (I would have liked to have a square one but they're too expensive for...

    Modified engine crewcab gas mileage?

    3.73/4.10 rear end gearing, what makes that livable and driveable is the modern overdrive automatic. My OBS Burb gets off the line great with 3.42 and the first gear of the 4L60E. Big truck has a 4L80E and 4.10s, it's pretty snappy once the grunt gets to the rear wheels, back in the previous...

    Owners manuals for sale

    Update: both 1977 owners manuals, the '77 Chevy truck accessories brochure, and the 1978 owners manual have been sold! I still have the '73 and '75 pickup owners manuals, plus several Chevy car ones from the '70s.

    Owners manuals for sale

    I found some pictures from when I first found it.... My Dad's 75 Sierra Classic had those rails on it; he painted the recessed part, that's normally black, Willoway Green like the truck was(with white top and side coves). Our '81 Sierra shop truck had the GMC version of those wheelcovers...

    Vintage mag question

    I personally wouldn't use it except for the spare... I'd be looking for another wheel like the other three. I know finding vintage aluminum mag wheels is not the easiest thing anymore....

    Owners manuals for sale

    I finally got out to the shop building and I do still have both of the '77 owners manuals and the truck accessories brochure for that year. I could do a package deal on all three if you're interested....

    Modified engine crewcab gas mileage?

    The skinny 16", load range E. 235/75-16? I called em pizza cutters. Once Dad and I got the front end fixed(new tie rods and sleeves, new lower ball joints, new pitman and idler arms) it drove a lot better.

    Chrome bumpers comparison ?

    The other difficulty may be finding a good chrome plating shop? I have heard that many are being forced out of business because of the very toxic chemicals involved in the metal plating process.

    Chrome bumpers comparison ?

    I have two later style square Burb rear bumpers, one with brackets too. Chrome is decent but they are OEM bumpers. The problem for us though, is shipping them from Houston, Texas to Connecticut....be more than they're worth.

    Bent fuel pump rod

    Fuel pump on a square body era small block should be AC #40987 for two line(inlet and outlet) and #41216 for the 3 line(with vapor return line). Yes I sold a LOT of these, back in the day, to still remember the part numbers this many years later. Installed a few too, with 7 squares in the family...

    Modified engine crewcab gas mileage?

    That was the one thing I didn't like about driving the '90 Burb on the road. No overdrive, just a turbo 400 behind a TBI 350, and 4.10 rear end. Originally ordered to haul a boat, and probably not real far.... It would max out at around 65 on the highway and it was screaming then. This was an...
