    Stripped bellhousing to transmission threads

    Noticed today that one of the bolts between my manual transmission and the bellhousing was very loose, basically the bolt was out. I believe I have an SM465. The bolt will go in, and sort of grab, but it doesn't snug tight. Seems like threads are stripped or compromised. Checked the other...

    1970 C50 2 Ton advice

    Thinking about one of these that is for sale on Craigslist. Anybody have any experience trying to get parts for these? Is it easy? The truck has front drum brakes. Can these be converted to discs or is that a major project/headache? If I buy it, I would be using it for hauling material in...

    PCV routing check

    Wanted to get some advice/verification on my PCV routing/hoses for an 89 454 TBI 3500. The odd part is I have two passenger side valve covers on the engine (past owner did this), so I have two valve covers with only a single PCV grommet in each. Presently I have the PCV valve on the...

    Broken lower kingpin grease fittings

    Looking for any suggestions from the wise folks on this forum. Both lower kingpin grease fittings on a Dana 60 front axle are sheared off. I don't know how long they have been like this. Things don't get too rusty in Colorado, so I think I should be able to back out the broken fittings...

    Anybody out there have ideas on what the combined truck/trailer/load weight rating is for my truck? Or if I can figure it out from the VIN or the codes in the glove box? I might get a used 10k rated trailer and wondering if this is too much for my truck or a good match. Its a 1989 V3500...

    Rear bleeder access trouble

    I'm embarrassed to ask because this seems like it should be so simple. But I'm having a terrible time accessing my rear wheel cylinder bleeders. Regular wrenches are too short. Tried the special offset, long brake wrenches and they are obstructed by leaf springs, brake line and other stuff...

    14 bolt rear hub seal advice

    Replacing rear drum brakes on an 89 V3500 dually which failed early due to gear oil plus brake fluid soaked shoes. Also replacing leaking wheel cylinders. I've read about these "improved" two part seals that can work better than the fixed seals. Any advice on whether the two part seal is...

    Driveshaft center support bearing questions

    The rubber around the center support bearing on my truck is a bit dry rotted and a small piece is missing from the bottom side. Do people think this is worth replacing as a preventive measure or should I just let it ride? If I push/pull on the driveshaft, there is a little play, but not much...

    TBI emissions control adventures

    Been reinstalling/replacing various emissions control parts on an 89 7.4L TBI where a previous owner had removed the AIR pump/pipe/valve system, cat, 02 sensor and various TBI vacuum lines were incorrectly hooked up. These parts are all back in. The AIR pump/parts were used but the cat, O2...

    Driving with leaking rear axle?

    Noticed today my rear axle on the passenger side is leaking gear oil from the inside of the wheel. The leak doesn't seem too bad, relatively slow. Is it a bad idea to drive on this at all or could I get by for a while so long as I keep the oil level up? Is there a seal to replace on this...

    What front axle is this?

    Hello - I'm relatively new to GM trucks and could use some help figuring out what front axle this is. It's on a 1989 V3500 that came as a cab and chassis. Is this a GM axle or a Dana axle? Any help is much appreciated. It has 10 bolts on the cover.

    Rigid plastic vacuum lines, can I replace with rubber vacuum hose?

    I need to replace a few vacuum lines on a TBI 454 square, including one that goes from the air injection diverter valve to the TBI, and a few others. But they are made of rigid plastic and are smaller diameter than typical rubber vacuum lines. Do I have to use rigid plastic vacuum line or can...

    My next project appears to be replacing the front output seal and maybe the bearing on my transfer case. Its been in my garage parked but left it in 4wd. Seems to be leaking a lot more when it is in 4wd than in 2wd and seems to be coming from front driveshaft area. Is this project do-able...

    Heater hose re-route around the TBI? Should I or should I not?

    How important is it for coolant from the heater hose to pass through the TBI on an 89 V3500 with 7.4L engine? While doing another project, I noticed that the heater hose connection at the back of the TBI is loose and looks like the connector plastic is partially broken. This is a heater hose...
