Hey folks, we are working with a 1998 C1500 with gearbox steering, having troubles with steering. when parked, the steering range is greatly reduced. soon as you move an inch, it loosens up. been in a couple shops already with several pumps and gears installed, kinda stumped. ideas?

I am curious too as my current 97 does this as well.

we are going to try and see if for whatever reason the CV axles are causing the binding tomorrow morning.

My truck is fine as soon as I press the accelerator

A 2006 Silverado I had used a "variable assist power steering unit". It makes it easy to steer when the truck isn't moving but then kicks out when you get any speed at all so that minor movements don't make the truck jump all over the highway. It uses an "electronic variable orifice" on the power steering line to accomplish this. There is a sensor you can replace on the steering column under the hood to make it work correctly again.

 

Search for "PT 20-0031.pdf" or "PT 20 -0024.pdf" for more info. Also "variable assist power steering unit" or "electronic variable orifice".

all your front joints greased up, ball joints, tie rod ends, etc., you dont have cv axles on a c1500 they are on k1500 as the "K" is four wheel drive, and "C" is 2 wheel drive, are you in snow country where even grease freezes

the owner is extremely particular, any issues are addressed immediately, and yes we are in the heart of canada but use synthetic grease designed for cold temperatures. one question i will pose here, will additional backspacing of the tires IE: aftermarket rims with incorrect backspacing, placing the centre of the tire outwards, have that much of an effect on this?

completely removed the variable assist orfice, in the event it was failing, and no improvement.

That's the same thing you should get when you are moving down the road because you don't need it once the truck is moving. You only need the assist when the truck is NOT moving. Try replacing it. It's fairly cheap if I remember correctly.

 

The part name is "Steering Wheel Position Sensor: "...monitors your vehicle's wheel position and turning rate" - my bad. The price is higher than I remembered but it's been a while.

      Oil Change

      By Erfar · Posted

      have you stuck with dealer oil changes since then? I made the same switch after getting tired of crawling around under the truck, but I’ve found some dealers are way better than others about getting you in quickly. Curious if yours has been good about scheduling or if you’ve had to look elsewhere for quicker turnaround.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thank you.   I am set on a 3.0 Duramax as my previous truck with a Ford Ecoboost had just as many, if not more, "common" issues.  Cam phasers, timing chain issues, 10-speed valve body and CDF drum, emissions issues, etc.  So I figured, why not get 2x the fuel mileage (these things got 27+mpg on every mixed city/highway test drive I put them through) and better towing capability with resale value to boot?   My minimum, shortest trip will be 50 miles 1-way and I regularly go out of state with a travel trailer.  I'm planning on using this for a marketing/event promotion business also, which would require regular towing of trailers for bands, DJs, sound and lighting gear, along with my personal camera gear for filming events.   Looked at other trucks in the $30k+ price range but the issues seem to be everywhere, plus too many with gaudy mods.  I'm literally sticking with RWD trucks because they tend to be actually used as trucks, vs. the 4x4 models I've seen with unsafe lifts, huge tires, and general mods that would affect reliability (I'm wondering if some of them were tuned, hence the aggressive throttle response and hard shifting).   So my goal is to find a stock, 3.0 with 1 or 2 owners, in good physical condition, and decently well maintained.  Can't seem to find that up here, everything in the $27-30k range has had multiple owners, smoke smell, issues, or body damage.  Or the ridiculously modified trucks with 80k miles for under $27k but lots of problems...

      OCI, not when but why?

      That’s pretty tough Grumpy. I reread the previous few posts. They all reference oil changes. Much like your last thread. In my humble opinion it keeps things interesting.

      Engine Wear and ISO 4406   1.) Cold Starts. 2.) High Particle Count. 3.) Low operating temperature viscosity and high low temperature cranking viscosity. 4.) Depleted AW, Friction and Acid packages.  5.) High engine load.    https://me.caltexlubricants.com/en_me/home/learning/from-chevron/heavy-duty-diesel-vehicles-and-equipment/The-Importance-of-Clean-Engine-Oil-and-Its-Impact-on-Equipment-and-Business-Performance.html   High particle counts have five sources. 1.) They are manufactured within the engine. Both wear debris and amalgamation of degradation products and combustion driven soot (worse in GDI). 2.) They are ingested via intake air. Ever hear the best oil filter is a good air filter? 3.) They are entrained in the fuel. 4.) This one is insidious. They are introduced in 'fresh oil'. 5.) They are introduced during the oil change.   ISO 4406 is the test that measures and quantifies the combine effects of all of the above particle related issues. You can mitigate your way into multiples of engine life by being attentive to them all.    https://www.hyprofiltration.com/blog/is-new-oil-clean   (from the link above)    [Quote] What Is the Recommended ISO 4406 Cleanliness Code for New Oil?   A good upper limit for new oil cleanliness is 16/14/11 (ISO 4406). Typical new oil usually has ISO codes of 19/17/15 or worse, which is far too dirty for sensitive components. This can be a major cause of degradation and premature failure.
