    Rough idle - vacuum

    I’ve sprayed carb cleaner on all the vacuum lines I can see to no avail. I did forget to check the canister. Wires are correct. Not sure of the fuel pressure or the compression. I tried hooking up a rented scan tool but it wouldn’t communicate (though no engine codes). I’ve just been driving it...

    Rough idle - vacuum

    Can I try capping the line going to the EGR? Or is that not gonna work to troubleshoot?

    Rough idle - vacuum

    I’m chasing a terribly rough idle. 1991 5.7 tbi 2wd. New plugs, wires, cap, and rotor. Was going to pull the Egr off to clean and or replace it. I noticed there is a line going to the Egr and then an open hole where there should be a vacuum line? Where does it go and could this cause my rough idle

    Tapping/ticking noise

    Hi there, I have a 1991 gmc Sierra 2wd Reg cab. No engine codes. Rough idle (been there a long time). New plugs, wires, rotor, and cap. Today it Just started making a tapping noise (sounds like metal on metal) on the driver side. Doesn’t sound like motor knock. Almost sounds like a rocker arm...

    Transfer case Front Output shaft seal

    Gotcha. Thank you. See when it’s the transfer case front output seal leaking - is it the pictures in the first post or second post. Thank you!

    Transfer case Front Output shaft seal

    Or am I looking at the wrong shaft? Is this the front transfer case output shaft?

    Front diff play

    I was under my truck today just to spray down the axle seals to see how bad they are weeping. While under there, I noticed some play (moving the shaft clockwise/counter-clockwise) in the shaft from the front diff to the transfer case. Is this normal?

    Transfer case Front Output shaft seal

    Finally got a chance to look at the seal. The actual seal itself looks ok to me…is there another seal in the yoke itself? Also, I don’t see a Center support or hanger bearing - do these trucks not come With one? Thanks

    Transfer case Front Output shaft seal

    Hi there, I just picked up an 1989 k1500. I’m ok doing a lot of the work myself but I didn’t feel like tackling the intake manifold gasket so I brought it in for that and an inspection. It does need some work, steering, CV joint, front axle seals, etc. It also needs the front output shaft seal...
