I've heard of vehicles that sometimes pull left but mine is pulling to the right and it's rather irritating. 2021 4x4 DRW. I just had an alignment done with bushings replaced to the tune of $300 and it's still pulling to the right, if anything it's pulling harder now than before. I see there's half a degree more caster on the right than the left but otherwise I don't see any other obvious reason from the alignment sheet. I've tried playing with tire pressures before the alignment and it had no effect. The truck does not pull when applying the brakes. The only idea I had that I haven't tried yet is moving wheels around. How bad is it? Enough you have to apply a constant counter force. If you let go you'll be out of your lane in 3-5 seconds.

Here's the post-alignment sheet, I don't have the pre-alignment data. Any ideas?

 

One front wheel has positive camper and the other has negative, so both front wheels are leaning to the same side slightly. It's in spec, but you got a ****ty alignment.

 

That's true, both front tires are tilted left.

 

You had them install new caster bushing to correct the camber issue, and this is the end result? Do you have the before printout?

 

Yes.

I asked for the before printout but the service advisor didn't have it. I'm bringing it back tomorrow.

 

If you swap front tires, does it pull the other way? My dad's 450 had a bad front tire and it would pull to whichever side it was on. If the alignment is sorted it's free to try.

 

Yeah I'm going to try that on the way to the shop in the morning. If the pull moves with the tire, it'll just be a different conversation when I get there

 

Donald,

How many miles? Any chance it is a brake caliper dragging? Pretty common after 50-60k miles in some parts of the country if you don’t pull the pins and lube with graphite periodically.

 

Something between 60k and 70k on the miles. I'll have an idea if there's a dragging pad or funky bearing when I swap the wheels here shortly.

 

Pulled the front wheels and swapped them around. In the process I checked bearings (good), caliper slide pins (good), that some work was actually done (it was), and felt for dragging. Both sides have a bit more drag than I'm accustomed to, but I'm accustomed to cars more than class 3 trucks. Also the drag was about the same side to side. Test driving after swapping the wheels and the pull is slightly to the left; not as strongly as it was to the right but it's clearly following the tire. The tires are still in great shape though so I'll probably just suck it up until it's time to replace them.

Now to figure out how to tell the TPMS system that those wheels moved.

 

When I rotate tires it only takes driving around for a few miles to figure out the new wheel position. There is a relearn procedure that can be done but it requires airing down and horn honking.

 

Oh really, is that relearn procedure optional?

 

On my SRW I haven't had to do it. Within a short period of driving, less than 20 miles, it figures it out. It might be different on the DRW but I would try driving it first.

 

On my ‘19 SRW it relearns by itself pretty quickly as others have stated. I don’t think a DRW would have any way of telling an inner from an outer rear wheel without some user input though.

The TPMS reset procedure for DRW is on page 403 of my owners manual.

 

Good to know, thanks. I only swapped the front tires so no problem there. Agreed I'm not sure how it would tell the duals apart, but I'm not sure I care as long as the side to side is correct.
