Had my truck jacked up the other day on the right front corner under the frame rail. I grabbed the cross member for the back of the torrsion bars and I could move the crossmember up and down inside the isolators. Is this normal or are the rubber isolators toast? I think they are bad because...

I just installed my brake controller in my truck. It used to be in my other truck. After installing wires and making sure it was hooked up right, the brake controller light will illuminate when driving over bumps. Makes no sense to me, the wiring is correct. Thanks

I want to put Oem size tires on my truck, 1990 k1500 short bed standard cab with 5speed and 305 v8. Reason being, I want best fuel economy and to accurately determine fuel mileage. I currently have 265s but they are doggy with the 3.42 gears. I always thought 245s were stock size but after some...

Well the temps have gone up to the 40s here for the past couple of days and have been getting rain. Yesturday I have taken the truck out and when I would go to use the brakes, the rear breaks would lock up when going slow with just the slightest touch of the brake pedal. Only thing I can...

I really want to put a 6.2 diesel in my truck, currently powered by a 305. My truck is a 5 speed, the 5lm60. It shifts nice and smooth. Will this transmission mount to a 6.2 diesel and handle it with no problem? The 6.2 will be kept n/a until I can afford to turbo it. If they do bolt and work...

About 2 weeks ago I noticed the u joint in my drive shaft at the t case was a bit sloppy. I went down to napa to get it replaced, I pulled it right out in the parking lot and they popped in a new precision u joint. I put the shaft back in and the truck was driving smooth as silk. This is my...

Went to go change the fluid in my 5lm60 today and found out it takes a large hex style wrench. Bummer, I don't have any hex wrenches that large. So I figured I'll have to hold off till I buy the right hex wrench. But I have no idea what size I need and I don't know if it's metric or standard...

With the poor fuel economy of my recently purchased 90 k1500 gasser, I'm considering a diesel swap. I'm a sucker for the good ole 6.2/6.5 Diesel engines and would love to swap one in my 5 speed truck. Should get great economy considering the truck is a standard cab short bed. The truck is...

I checked for codes on my '90 Chevy k1500 with 305 since the check engine light is illuminated. The codes that came up were 34 and 45. What do these codes mean and what could be the cause and fix for them? The truck will sometimes have a lack of power and will buck or hesitate. The truck...

I hope this is the right section for this, if not please move. The current motor in my '90 K1500 has a knock in the lower RPMs. I would like to replace the motor with a newer vortec style 350 motor but at the same time I would like to convert the vortec 350 to a 4 barrel carb. What's...

I recently bought a k1500 5 speed on the cheap. The 10 bolt rear is toast after driving it for a week. I called the local salvage yard for a replacement. They had a 10 bolt and 14 bolt. The 10 bolt was shot, they said the 14 bolt semi floater will work fine and it is the same price. So I...

I got a new differential cover for my rear end. It came with a new gasket. Ive never used a gasket there before. Am I safe to just use the gasket alone or use the gasket with RTV? Should I just use RTV alone? Thanks

What is the best or recommended fluid for a half ton 1990 Chevy truck? How much fluid is needed? Im not sure if it is a nv3500 or nv4500. Maybe someone can fill me in on which one I have. It's a V8 gasser. Thanks

The other day I test drove a '94 chevy light duty k2500. It has been lifted, all new ball joints and tie rod ends. The tires are 33" tall and pretty much shot. I was told it needs a front end alignment. The problem is while driving down the road, the front end likes to wander left to right...

I would like to have my original injectors rebuilt, I swapped them out with rebuilt ones about a year ago and want the originals for back ups. No shops near me deal with the 6.5 mechanical injectors. Looking to hear where you guys send yours off to, to be rebuilt. I'm looking for a...

Well my truck has been sitting at the mechanics for close to 2 months now for repairs to the speed sensor/shifting issues. He never fixed it so I had enough. I decided to take my truck back home, finally. After a few miles of driving, out of no where I hear what sounds like an exhaust...

What am I getting myself into by swapping a 96 motor into a 95 truck? The 95 is A 5 speed and lacks a starter and alternator. The 96 is from an auto and has everything

What is the purpose of the speed buffer? If it goes bad what are the symptoms? Where can I source a new or working unit?

Been thinking lately about going with a gooseneck or 5th wheel hitch. I'm not sure of the major differences between the 2. Is one better than the other? Is one more superior than the other. Does my bed have to be installed on the truck to run either hitch? I'm asking cause I'm interested in...

Last month i swaped out my np243 case for an np241 t case and had problems with it shifting properly and the speedometer was reading way off. Shifts very hard at high rpm. Brought it to my mechanic to figure it out and he claims that it will not work right because I don't have the encoder...
