Speedometer Cable and Tail Lights
M1009 - Found and fixed an annoying rattle that would only show up when stopped in gear
. Been living with it for months. It was a doozie to diagnose. Sounded loud and clear in the cabin. Chocked the wheels, locked the e-brake and poked around all under the dash trying to find it. Finally found it, under the hood. Now I now why GM put that clamp on the booster hoses under the master cylinder. If the metal part of those hoses are in contact with each other and not secured, they rattle and ring like a bell out of tune. That clamp is missing on my truck, so anyone know where to get one? Now, the only rattle left is the ashtray. Going to fix that one soon. Really quiet for a diesel in the cabin. Can't wait to see how quiet she is with the hood insulation I am going to get come Spring. Repaired the drivers side backup light. Now I can see on "my" side of the truck when backing up

M1008A1 - Cleaned up the dash today. Replaced all the bulbs and got everything working. Now, the e-brake light and 4wd light are working again
. Had to repair the volt meter light socket. The crimp was pretty weak from the factory and pulled right out with no effort
. I soldered it back up with the assistance of my lovely bride. Replaced the speedometer cable with AC Delco #88959481 sourced from RockAuto. This is the superseding part to our original equipment piece. The speedo was doing the "dance" in the cold weather. Figured it needed to be replaced. Haven't had a chance to test it yet, will report back as soon as that is done.
Replaced the taillight assemblies on both trucks with TYC 11-1282-01 (Right) and TYC 11-1283-01 (Left) also from RockAuto. Nice pieces for just a few sheckles. From posts and pics I've seen these same pieces have been sourced from LMC for a few sheckles more.
Next up - Replace the radiator (pinhole leak) and defective block heater (Kat's from NAPA, got replacement under warranty No Questions Asked) on the M1008A1.
These trucks are incredibly reliable. Very low mileage, fuel efficient and loads of fun to drive. The more I do to them, the better they get.
