Truck jerks to left while driving.

Is it possible to run a shorter belt and bypass power steering pump? Not sure if the cost of a new belt is any savings from having a professional check the rack out.

Well i'm almost 100% sure I found my problem, The Passenger side CV Shaft apart on me thursday night. ( outboard joint )

 

I removed the broken section, left the stub in the hub, and replaced it the assembly saturday afternoon with a new CV shaft.

 

I had no indication that the joint was failing, no clicking, no unusual noises, no torn boot or grease flung every wear, no unusual movement when i checked the front end this week. I had the front end in the air, spun the wheels straight and at full left and right turn, forward and backwards.

 

With the CV shaft removed i didn't get the jerk to the left anymore that day, it jerked a few time in a row right before it came apart!

i was surprised to see that the boot held all the ball bearings and cage inside of it, so no extra damage was done.

 

Thanks for all the input and suggestions. You guys have been a great help.

 

Cheers

Would not expect a failing CV joint to be the cause of sudden pull to one side. Even if the CV joints were causing the right side wheel/axle to slow down, that would cause the truck to go to the right, not left.

Hopefully this was the cause of the pull.

I did not suspect a failing CV joint to cause something like this either. Maybe it's not my issue, but it came apart anyways. it has not done the jerk motion since i took the CV shaft out and installed the new one... cross my fingers that's what it was.

 

Thanks again you guys.

 

I'll keep you posted on what happens if it comes back.

 

 

Cheers and Merry Christmas

If it's lifted then maybe it's the infamous death wobble but a little more controllable then what I've seen where it jerks back and forth

I know this is a kinda old thread but I'm having a VERY similar issue only jerking to the right. 07 NBS silverado, 72k miles. Driving straight, turns, doesn't seem to matter, I get a random "jerk" in the wheel, pulls hard to the right. I do have an APT at the dealer in the morning, but just kinda wanted to research the topic some. I assume your truck is still running well since the CV repair?

 

Thx,

 

Dan

      Tire psi

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      Some Assembly is Required

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.
