    Front Axle issues

    Sounds like it fell into 4wd to me. Lights nor working on the switch is usually in the switch itself. Make sure you have right switch. AWD switch and 4wd switches are not interchangeable. Fuse blowing if not caused by incorrect switch would be bad actuator at transfer case or front diff. I'm...

    1997 K1500 z71 suspension help

    Seems to me you have a lot of clearance between the fender and top of tire. I suspect someone cranked the T bars up. Look at how far you are from the stops at the upper control arms. May be hitting the stops.

    Hvac motor confusion

    Refrigerator coil cleaner is a great way to clean the evaporator without pulling the box out. My k1500 wasn't pushing any air and I found it matted with dog hair.

    Thump thump, G80 and confusing gear oil

    If you have up-and-down play in the wheel bearings, you need to start with the bearings

    1994 C1500 Fleet Truck

    The earlier model V-8 drivers side manifolds had a single wire O2 sensor on the drivers side. When they moved the O2 sensor the put a 3 wire heated O2 sensor on the y-pipe in front of the cat. in 1996 the vortec engines used dual cats with four 4-wire monitored o2 sensors. Word of caution, if...

    94 K1500 blowing 4wd fuse on startup.

    That circuit goes to the transfer case too. I also remember a loose spade connector in the far back corner of the engine compartment by the brake booster that isn't connected to anything. Make sure that isn't touching metal

    Eng 1 fuse blowing

    That happened on my 97 k1500 after unplugging every sensor short was still there. I opened up the fuse bow and once it was open the short was gone. One wire had a rub so I drove it home put liquid electrical tape on it and called it done. 4 months later I was driving it with the front fenders...

    Gmt400 Escalade

    I paid 2k to have the seats redone. Plus sized the wheels to 18" replaced the headlights but buffed the originals and reinstalled them when I realized the adjusters didn't line up with the access holes on the rad support

    Gmt400 Escalade

    It sounds like a u-joint to me. I'll assume you cruise in AWD. If you feel so inclined, pull the shaft and rock both joints all the way back and forth in both directions if you feel any resistance replace both joints. In the meantime put it in 2WD, the shaft should not spin while driving.

    98 305 cranks, doesn’t start

    If it is a security system issue, I found 2 trucks that had lost power going to the Power Steering/security fuse I jumped power to the fuse and it worked. I have no idea why there is a fuse for the power steering, but got 2 trucks started like that.

    What to prepare for before I rip into engine....

    If you've changed all ignition parts and have good compression then it's in the injection system you have to pull the intake to access it and you will want to upgrade to the Moro setup with new gaskets. That is unless you are wanting to upgrade to 350.

    Tech: 88-89 GMT400 Quad Sealed Beam upgrades (Bosch T84 E-code headlights)

    I found this thread about 6 months ago. I've been hell bent on finding these Bosch inserts ever since. So I bought 4 Hi beam lights from Ebay for $50 each and continued to look for the low beams. After much research I've found that the Left hand rule of the road low beam lights are gone. I...

    1997 RCSB build on 4dr tahoe frame

    fair enough, it is his spreadsheet. I'll just have to be patient. just noticed that the last few requests posted didn't seem to have any follow up posts indicating that contact was made and didn't know if he was still active on either site. good luck with your build.

    12200411 PCM swap for 1996 to 2000 GMT400 trucks

    I have done that on ls1trucks and here. I will give it some time, just wanted to feel out if there were alternate avenues in case lextech was no longer doing it. I would also like to know what I'd need to tune the ecu after I'm done. can this be done with a snap on scanner? or must I buy another...

    12200411 PCM swap for 1996 to 2000 GMT400 trucks

    hey all. I am interested in the spreadsheet/pinout for installing the 411 ecu in a 97 silverado 5.7. I've pm'd lextech, but in case he is no longer doing this, does anybody have the information available? I'm sure that I can figure it out by studying the 2 wiring diagrams, but if he has already...

    1997 RCSB build on 4dr tahoe frame

    Hey good luck with the build. I was going to comment that the frames are different, but you've addressed that concern with knowledge. I would be interested in the spreadsheet or pinout for the 411 swap. haven't been able to reach lextech, and I've already got the ecu and connectors with...
