I have the 3500 so there may be some differences between the problems
Tailgate falls open on rough roads (TSB on this)
Idler and Pitman arms need replacement about every 2 years.
Alignment probs due to above problem.
If it has oil cooler the adapter leaks a lot and I've had to replace
several gaskets on it.
4X4 actuator is heat activated, generally speaking, replace it with
Serpentine belt tensioner needs replacement pretty frequently, every
100,000 miles ( some may not consider that a problem).
AC accumulator located low pressure switch goes out two or three times
That's all I can think of.
Oh, forgot to mention. I install a set of four Rancho RS9000's on my
3500 just a couple of months ago. It's a 1992 and it was riding
pretty rough. The Ranchos really smoothed things out...as did a new
set of tires and the front tires and wheels load balanced (GSP-9700 at
Discount Tire for $20 a tire). Wow, what a ride now!
Slip yoke is a given, never had any problems with brake rotors. The
self-adjusters on the rears rarely work which can cause the fronts to
overheat/overwork which will eat pads and rotors. I rotate my tires every
6k and check the rear brakes every time. If you remove the top spring on
the rear assembley you can get the self adjuster out without having to
remove the whole assembley. Disassemble the adjuster, clean the threads
with a wire wheel on a drill, and apply a light coating of nev'r seize and
they should be good for a few years.
Fuel tank sending unit (not the pump, the octopus lookin' thing it sits in)
has a tendency to rust out where the lines exit the tank, so keep an
eye/nose out for that one.
Taillight circuit boards will inevitably grenade and cause your rear lights
to go wacko.
Aside from normal wear and tear items, those are the only "common" problems
I can think of.
Great trucks, durable as all hell and will run forever if you take care of
as far as the taillight circuit boards go , Does anybody know of another
source for new ones at a good price? I've seen them on ebay for around $20
each. Anyone know of a better price? I sort of remembering someone saying
they got them for about $25 per pair.
Thanks for the info,
mine are starting to look pretty ratty and will be replaced soon. Also, I
always see new taillights for fleetside trucks for my truck (90 k1500). To
me, the lights look the same for sportside. Anybody know for sure?
I have a '93 Silverado 350/SB-Step/4x4/Auto.
So far, here are that things I have had to replace in the last couple of
years. I listed the price I paid, including labor:
- Brake discs (twice, $50 each pair). They keep warping! I keep wondering
if I should get the slotted or drilled discs to help with cooling.
- Radiator. ($130) The entire bottom half of the core was plugged up. I
was told that this is normal in hot climates (Arizona). From
recommendations in this group, I bought a Modine replacement and it has run
ice-cold ever since.
- Water pump. ($50) The seal died.
- Fan clutch. ($40) The old one started free-wheeling all the time instead
- Pitman arm and idler arm. ($150) My mechanic told me that 4x4 Chevys are
notorious for idler arms going bad. My steering is tight again!
- Door hinges. ($90) He said that ALL Chevys are notorious for door sag
due to worn bushings.
- 4x4 actuator in the front diff. ($280) He said that the new one is of a
new "generation" that will last longer than the original design.
It still has the original engine, transmission, and transfer case, and they
have not been rebuilt or ever given me problems, except for recent low oil
pressure in the engine. I'm checking into that. Still, for a 10-year-old
4x4 that has been WELL USED on and off road, that's not very much stuff to
go bad at over 160,000 miles. It only adds up to a couple of payments for a
NEW truck. I'll just keep my old one going. I hate the style of the new
step-sides anyway. The steps are useless. One foot, sideways (maybe)...
