Upper control arms close to tire after lift

No I had literally just bolted the wheels and tires on when I noticed that

 

Yeah, first step is to align it. All that will move around a bit so it may get better (or worse).

 

You should have no relative motion between the tire and the spindle unless there is play in your wheel bearing. Alignment won’t change that dimension. If it’s not touching now, it never will unless you bend a wheel or the spindle itself, or your wheel bearing fails.

 

Then my understanding of how a dual A arm IFS suspension works is wrong, and I don't think it really is.

The shorter upper control arm will pull the top of the tire/spindle inwards (decreased camber) at full droop, and because of the shape of the UCA and where the BJ pivots, it should be getting closer to the UCA at droop.

 

Auto Zone 1/2" spacers and Toyota Matrix studs will cure your issues.
Been there, done that.

 

Mine pretty much looks the same. Where are the rest of the pics? Looks good already.

 

Going to do the rear tomorrow. You not running spacers or anything?

 

that is about the same as my Ram 1500 was right out of the box with 20x9" wheels and what ever size tire came on it I cant remember now. Then I put 35-12.50-20 KO2's on it a couple years ago and none ever rubbed. I bought a set of hub centric spacer that were only 10mm thick but didn't use them , another $200.00 sitting on a shelf. I would run it

 

I see where your head’s at... it would be a good idea to check it at full droop. The tire/spindle relationship stays the same throughout the suspension travel, but taking a second look at the pic, I can see that the UCA could potentially touch the tire as the ball joint pivots. Depending on how far it pivots.

 

Did you install the SPCs with the default setting of position D? Doesn't look like it. I suggest setting it to D and taking @jbrandt's advice and get it aligned. Let the tech work the lower cams and see where he can get you with those wheels.

The backspacing is definitely going to be an issue - you'll hit the frame for sure - possibly more. Backspacing for our trucks is 4.50" 2nd/3rd gen is 5.25".


for reference -

truck on its own weight, 255/85/16s on 3rd Gen 4Runner 5 star wheels (approx 4.625" Backspacing), OME 881 with nitrochargers, SPCs at position D.
Caster 3.0 LEFT, 3.4 RIGHT - Camber 0, Toe 0

Going to take it back in and double check alignment - just added an ARB Bumper (no winch) and the front did drop slightly as expected. Want to be sure numbers are still good.

 

Wonder if this has anything to do with it (?)

 

Nope no spacers. What size tires are you running?

Yeah whats going on there?

 

I have it set to D per the instructions I think. The star washer thing is perfectly flush with the underside of the UCA. The curved end of it is facing inward. Now, I do have room to push the ball joint towards the inside of the UCA as it's sitting all the way out here:

 

Did I put the on the wrong side?

 

Good info. So, looks like I'll need spacers. It's not my daily driver so having to leave it on jack stands to take a wheel off and have a tire repaired isn't a huge deal. I may also look into replacing the wheel suds with Toyota Matrix wheel studs.

 

Idk, you may not. I used to not be able to get my fingernail inbetween the tire and ubj, as far as I understand, that distance never changes. A 1" spacer will clear your stock lugs no problem. Thats honestly the easiest route.

 

No that looks right, Im looking at the silver thing on top of it. Kinda looks like a diff drop spacer.
