    C5 Wheels on 2/4 Dropped SCSB

    Has anyone here seen this done? I may end up going lower if I get the wheels but I wanted to see what they looked like before going forward with it.

    98 C1500 5.0 TO 5.7 SWAP

    The entire butterfly valve was bigger on mine, I caught it when trying to swap over parts from the 350 tb to the 305 one since my 305 tb was in nicer shape. Idk maybe one of the many previous owners used a throttle body from a v6? Either way, worth looking into.

    98 C1500 5.0 TO 5.7 SWAP

    I recently did the swap, the throttle body was bigger on the 350 than the 305. The 350 has two catalytic converters but the maf will adjust for the extra cfm. Can't think of anything else.

    NV3500 information

    Idk how the reverse lockout works, but I thought it was weird that reverse isn't synchronized on these transmissions, at least mine wasn't, I understand some were. They have the cone machined but they skip the synchro ring, the reason your gears grind when you go from forward to reverse. You...

    Brake switch getting hot blowing fuses, signals clicking

    Turns out the new bulbs i put in the cab lights were incorrect, that seems to have fixed the fuse and hot brake pedal switch. Still stumped on the clicking signal relay. I don't see anywhere that looks heat affected other than the relay i swapped out.

    Brake switch getting hot blowing fuses, signals clicking

    I have a weird one, my turn signal relay was clicking without the signals or hazards on. The hazards and blinkers still work, they turn on and off as they should, but the clicking noise from the relay doesn't stop. I pulled the signal relay, and the relay's outer cover was melted. Replaced...

    Driver Rear Parking Brake Cable Adjustment?

    I just went through something similar with my driver side cable. I adjusted it and one brake was dragging, turns out the outer seating on the cable was bunching causing it to stick. If this is the case on your truck you should see a bulge in the cable where it's bunching up.

    Shimming Carrier Bearings for Backlash, How Much?

    I'm putting an Auburn limited slip in my gm 8.5" (3.42 ratio) and my backlash is currently 0.015" (too wide, ), looking to get it between 0.005-0.009". Is there a rule of thumb for how much shim I shift from the left to right to how much backlash I will reduce? I have a shim set with 6...

    Turn Signals Work But Flasher Relay Continues to Tick

    Anyone encounter this issue? The signals and emergency flashers come on and off as they should but the relay continues to tick as if they didnt turn off. Ive replaced the signal relay and the new one does it too, the old one shows signs of heat as the relay outer cover was melted.

    '96 5.7 vortec random idle changes

    My guess is throttle position sensor. They're cheap and you can swap it out in the auto parts store parking lot.

    1998 c1500 5 speed possible clutch problems

    On the nv3500 1st and 2nd gear use 3 piece synchronizers, 3,4, and 5 are 1 piece, and on most of them, reverse isn't synchronized. 1st and 2nd should grab quicker because 3 piece synchronizers have more surface area. Could it be the difference between the feel of the synchros?
