    Another exhaust options thread - what should I do?

    So I’m tired of the noise the exhaust makes when I’m idling at a light and the general rattle. It currently has the stock y-pipe, end of it goes out the driver side, not straight back. There was no catalytic converter on this version. It’s a longbed, single cab, 2WD, camper special. I have read...

    I really want to replace the front brake lines and hoses but as it goes for everyone, been a real bitch to get the flare fittings loose on the lines and at the proportioning valve. No issue getting the lines loosening on master cylinder. My question is, if I unbolt the proportioning valve or...

    This is a coolant leak right?

    I just want to verify this is the radiator leaking coolant. I drained coolant and ran a system cleaner. Drained again. Replaced both hoses, radiator cap, and thermostat (195F). Refilled with fresh coolant and ran until no more bubbles, about 30 min. Took a quick 5 min trip and popped the hood...

    There is a chirping or squeaking sound coming from the inside of cab near instrument cluster. Sounds like it corresponds to something rotating, gets faster as wheels turn faster. I think it must be the speedometer cable…anyone experienced something similar? Here’s a link to the video for sound:

    AC troubleshooting

    I’m curious the best way to start assessing the health of the ac system I have. This is a factory AC, doesn’t have a belt installed currently. Should I start there and install a belt? Is there a way to check if the compressor works? The guy I bought it from never even tried it, 20 years and...

    What to replace while doing tie rods?

    Will be replacing my tie rods (inner and outer with sleeves), as well as idler arm and pitman arm. Should I knock out the lower ball joints what I’m at it?

    Do I need new door hinges, springs, or pins/bushings?

    1980 gmc c25 Hi, My driver-side door sags pretty bad, still closes but it’s a real pain. A lot of time the little wheel washer things catch on the spring also. When I’m inside the car I can see a very large gap at the top of the door. I’m afraid it’s just going to get worse and I won’t be able...

    Fuel tank sending unit broken hose

    I noticed between the cab and truck bed that the hose is split on the driver-side fuel tank sending unit. I don’t know the best way to fix this and how big of an issue is this? Do I need to remove the bed to fix this? I don’t really see how I could access the hose any other way. I’m unsure which...
