    Stumped on oil leak

    Yah, the sleeve could be worn too. I like the blue gel anaerobic thread locker on the cover as a seal. If it's worn out wrong or the main seal is effected, buying a quality or sourcing an OEM cover might be required. Sometimes they punch the main seal off center for the bolts. This could be why...

    Power steering gear box

    Good advice 75gmck25. Same same or it might not work, 4wd vs 2wd of any of the older pre-90's model years. The Pittman arms can vary as well, so do your research at Rock Auto before you buy. Off Road Designs sells the best of the best USA replacements. In this day and age, you might have to...

    Lift or rebuild stock?

    That's what I'm saying too... the ride is very dependant on the C/K version. You really should use 2 floor jacks and witness the ball joints and steering system is within limits with the jacks at a very slight lift over the worn suspension to gauge the required spring rates and extra leaves...

    Rim compatibility

    Yah, the only issue with going 16", is every ranch horse trailer in world uses them too. The odds of finding a good used one in a pinch are getting tough. Especially during the summer when people and horses travel until the fall. Spare 16" good used tires are like hen's teeth in the mid-west...

    Death wobble, or bad wheel balance?

    Agreed idahoevette... If you stripped the pitman because of the toe issue, you might be missing a few teeth on the Saginaw shaft/pitman connection... which could have blown out the ball joint or vice versa. If the Saginaw Steering box was ever "adjusted" to remove slop, (like I did on my...

    Need help finding replacement rear shock mounts

    Just to be safe, disconnect the battery at both terminals before you weld it, OK? You might not have a battery burn up or a starter solenoid get fried, but I have seen the doors try to weld themselves to the A-Pillar before. Sensitive electronics might not like it either. You'll want a welding...

    Stumped on oil leak

    Yup the hammer. Lil' patience, not too much torque, some gasket on the brush for every bolt thread and just enough gasket sealer on each side of the paper to make it sweet, not squish. The secret some transmission guys use, is to make certain there is a good round gob of gasket sealer directly...

    Transmission cooler ideas

    Yah wanted a Tremac very badly. After careful inspection of the OLD Derale units I have and the expensive cooler I bought, the unit I bought is the more expesive style 40 stack. The cooler they are installing into the fabricated units with fans, is DIFFERENT quality and a lot more money. The...

    WTB Shifter *** Thread Temporarily Reopened for SquareRoot *** Shifter Aquired.

    Custom aluminum Dash. It's not completed obviously. Better pic of the stand: Lot's of wiring, then the punch list of details and tests. 90 degrees in the shade. We had snow 7-1/2 weeks ago.

    SquareRoot Lokar installed: Custom pedastal made from 4 Duce Plate. Had to scarf the side of the pan to make it work underneath.

    Transmission cooler ideas

    My build got the Derale: https://www.summitracing.com/parts/DER-54078 12.75 in. x 13 in. x 2 in My 4L80E has larger diameter lines than the 700R4 had, so plumbing through the radiator and using a standard cooler was out. Shrinking the lines means poor circulation. Had to go stand-a-lone, so...

    Electrical dash wiring / wire color issues.

    UPDATE 2: The diagram for the 87' Blazer is the 88' Blazer for wiring fuel system too. https://chevytalk.org/fusionbb/showtopic.php?tid/310389/ It looks like the pump gets a gray wire or a tan/wht wire, depending on the year and has various grounding scenarios. Sometimes the pump is made hot...

    Electrical dash wiring / wire color issues.

    UPDATE: Found this photo, with a much better detail on the pin out for the 1227747 ECM in the 1987/1988 RV: It shows the Orange with Black stripe as the 700R4 Neutral Safety ECM wire. This picture above is completely different the the 1987 Typical wiring harness diagrams. This diagram below...

    Electrical dash wiring / wire color issues.

    I'm rewiring a custom dash in my 1987 Blazer. I'm used to just using my Amprobe with a pair of wire spikes and verifying these things as I need to. Without power with so much of the dash opened and with thin gauge dash light kit in a custom aluminum entire dash console and dash board, I'm in...

    Auto A/C vacuum pump. lots of CFM or Less CFM whats best?? A/C tech's please help.

    I'm not perfect or feel the need to to be correct all the time. I'm learning constantly. Please teach me how what I wrote could be improper? Not a physicist... not an engineer... just a human that cannot stand planned obsolescence. Please test the cheap $89 ebait pump with a quality Winters or...

    Auto A/C vacuum pump. lots of CFM or Less CFM whats best?? A/C tech's please help.

    RSMII, Your 1980's pump is probably not the one from Ebait for $89 made in China, is it? At 5000 ft, the transmission test manual states the vacuum potential will be less due to elevation, "AT THE RATED HP OF THE ELECTRIC MOTOR". ...and it is. Now imagine the Chinese gentleman who rated the...

    Auto A/C vacuum pump. lots of CFM or Less CFM whats best?? A/C tech's please help.

    Verify the pump works ASAP, is my best advice. This is not really a professional unit like you would find at Grainger. Few A/C charges a year and some bench time for a transmission rebuild for Valve Body testing, like shows in his videos, is why I opted for this version. If you are serious...

    Are OE lug studs long enough? 77 C10

    Aviation AP Mechanical standard is at least 1 full thread protruding from ANY and ALL fasteners, (with proper washers, as required). Zero deviation. Anything less is 100% failure, gross negligence on the mechanic. Some GM lugs that use a plastic cap are intentionally over-sized so they do NOT...
