KDSS dealer/warranty issues

Is it just me?

Nope.

Biggest change I noticed when I swapped my rear springs (which was giving me 1.5” of lean) was that the torque steer went away. Different cause but similar effect. Step on the gas from a stoplight with your hands off the wheel and see if it pulls. Then let off the gas and see if it pulls the other way. If it’s straight on and off the gas without any assistance you should be in pretty good shape.

I'm real curious about this. Which way did your truck pull on acceleration? Ever since I had an OME lift installed at Slee in March of last year, damn truck pulls hard right on acceleration. I would certainly hope they didn't put the tall spring on the driver side but is there any way I can tell if they did? Are the springs marked in any way?

Sorry for the hijack

Eh.... not so much on the warranty. The spec, I've been told, is .5" on level ground with a full tank of gas. Which is still a lean and the rig looks crooked if you're looking at it. If you fall out of that spec dealers will try an adjustment/bleed under the 3yrs/36 factory warranty. If you're in that spec they won't cover it. Mine is in spec when the tank is full - but changes to 1" otherwise.

I asked and was also told that the Extended Service Agreement from Toyota would not cover "adjustments" like that. Regardless of the spec - only if the system failed would the extended "warranty" from Toyota would cover it.

As others have said... it's best to try to fix it on your own- dealers are pretty much useless to help on this under warranty. Warranty is very limited in scope on this and the dealers won't have the time nor desire to keep trying until they get it right..

I do not rely talking about, but you have 1005 warranty bumper to bumper if you do? do you? if so then Toyota dealer will fix for free to you.

I have to measure my and see what you all talking about. I know that any of my Toyota LC and I have 3 of them will have a sag .

This is what folks are referring to... The lean typically comes with lifting and accessorizing but it's known to occur with stock rigs too.

@Tripledave - I don't remember which way it pulled. It was not aggressive though because I didn't really even notice it until it's gone.

After driving about 50 more miles on it, I've noticed the biggest difference is when I hit a bump on the (formerly) low side - driver front - I no longer have a pull in the steering and a unruly response from the suspension. Front left hits seemed to require a lot of correcting, now it's like any other car.

Without deep-diving into the engineering aspect, this generally seems to make sense. If the KDSS wasn't reducing sway/lean on that side of the car because the pressures were off, a bump and subsequent sway/lean would likely be exacerbated and cause secondary and tertiary issues - steering, additional sway, added work for certain parts of the suspension to compensate for additional sway/lean, etc etc.

@Tripledave it pulled right on acceleration and left when i let off the gas. The truck was 1.5in higher on the left side, so it made sensd, kind of like if your right leg was shorter than your left you'd walk in a clockwise circle Sent from the mobile client - Forum Talker

My 15 had a 1.5 in lean in stock form that was excaserbated when I put the OEM strut spacers on it. I spent a ton of time (including a trip to the dealer for them to scratch their head at it) to ultimately determine it was an issue with the factory suspension. I could get the lean within a half inch in a static situation in the garage but as soon as I drove it, the lean would return. I put an OME lift on my truck right before going to Breckinridge this past summer and there is 0 lean. The only thing I can imagine is that something (possibly sagging spring) in my stock suspension wasn’t holding up. For what it’s worth, I was beating my head against the wall and was pleasantly surprised that the lift “fixed” the lean.

@vapilotda - did your dealer do the vehicle tilt check? That's what they officially called doing what I did in my driveway. Obviously they found nothing... just curious what their reaction was? The scratching the head and doing nothing except trying to shake you down is standard.

Who did the install? Is it possible the installer was a KDSS savant and got it sorted out and the timing happened to coincide with the OME add?

 

[vapilotda]

The dealer did the same adjustment procedure posted here. They were able to accomplish the same results I did (inch or less difference static) and didn’t charge me for it. They admitted they weren’t familiar with the truck and system at all.

I put the lift on myself and did the KDSS procedure as I’ve done many of times before with perfect results. I’m not saying to put a lift on your truck to fix it. I was just under the assumption that my cruiser with 35k miles wouldn’t have a potentially worn out suspension part but that seemed to be the problem.
