GX460 - Rub Issue (1 Viewer)

[NOLACC]

I’m having some issues with rub - sounds like scratching or scraping, but pretty sure it’s rub…

2019 GX460 Luxury
-Bilstein 5100s
-Dobinson springs
-Freedom front control arms
-265/70R18s BFG KO3s

If I’m coming in a little too hot on a curb, I’m getting a rub - but it actually sounds more like a grinding sound. Also the rake is a bit out of wack… Maybe I could do a spacer to level the front a bit?

I have two 2019s with the same set up, the other is a base - zero rub.

Any suggestions?

I don’t see any rubber on the running boards, which are coming off soon… So I’m just trying to figure out the best solution.

PS:
Don’t beat me up on the “bronze” - I know it’s a bit too gold. I’m going to re-shoot the wheels to tone them down… Mind you, it’s pulled up on a curb in two of the pics.

I bet you are rubbing on the fender liner above the body mount in the back of the fender. You might rub on the body mount wing itself with that tire size, though I think stock offset should clear the metal.

I have 285/70/17s on -12 offset wheels which required a body mount chop. They still rub on the rear fender liner plastic in certain scenarios where the wheel is turned and the suspension compressed. Rubbing on the plastic actually sounds worse than when it was rubbing on the body mount.

Chalk test time. Cover the fenders with chalk, simulate the scenarios in which the rubbing sounds occur.

I don’t know if this sounds crazy, but it almost sounds like my springs are rubbing against the new upper control arms?

I see no signs of tire rub on plastic, is it possible that it’s flexing enough for metal to metal components to touch? I wouldn’t think that’s possible…

My other GX is one tire size down, but that’s less than half an inch taller - which could possibly make a difference.

tire clearance is a game of millimeters so the 1/2 inch smaller diameter likely makes the difference. When my tires were rubbing the body mount, it was a pretty distinct tire-on-metal sound. When they rub on the plastic fender liner it actually sounds way worse. That fender liner is flexible and there is some space between it and the pinch weld so I think when it rubs it can push the plastic back which may minimize how much wear you see.
You should be able to see wear on the body mount paint if you are rubbing on the body mount itself.

First off, love the bronze wheels! Have them on my rig, below. Yeah, you may need to get them a little dirty to moot the shininess a wee bit.:

Regarding rubbing.
Rubbing will usually be:

1. On the fender.
2. On the inside of the fender liners.
3. On the body mount.

A couple of cures are:

1. Do a BMC, very common and cheap with both the 4Runners and GX's.
2. A positive back spacing (moving the wheel further out/away) with either wheel spacers or offset wheels.
3. An alignment that pushes the camber forward. This worked for me since I have a high clearance front bumper, but may not work for you with your stock front end.

Leveling out your rig will not resolve the rubbing if you are in compression when turned in and the nose dives. You'll still get rubbing. You just won't get rubbing during most of your day-to-day driving.
Hope this helps!

Thanks, I found the perfect color Toyota bronze color code with eggshell clear - which I shot on my silver one… I went a little lighter on this one, so slightly more gold than I wanted. I was trying to match the LC200 heritage bbs bronze. I usually go with black wheels, but I wanted to try to play off the pearl. Who knows, it may grow on me after chrome delete and victory blitz front bumper is installed. Wish I could find a legit source for a gloss black webbed grille.

So the problem is (well what I’m hearing) it happens when I’m cutting into a parking lot, or a gas station, etc - just for instance. Also when I’m backing out of a parking spot, reversing into the street over a curb… So basically anytime I’m flexing, and it doesn’t happen when I’m creeping.

I do wish the rake was a bit less severe in the front. I’d prefer not to do a chop. What about swapping out any of my front end components for something that will lift the front up a bit more? Have yet to take measurements.

I just hope it’s nothing to do with my suspension setup, and it is tire rub. It is slightly concerning though… comes with the territory.

Were any OEM style bushings loosened and then tightened only with weight of the truck on them? They should have been. If not maybe its some sort of freak binding situation or rotation due to the higher stresses.

Good point, I didn’t even think that. I’m so use to the ease of my old LCs, as similar as they are to… they’re different to GX mods.

Truck is definitely leaning a bit also - even with the new suspension. I’ve always gone OME or Bilstein. We are going to put it up in the air this week… my other 19 is a base, zero issues. Running 275/65R18s.

Just pretty frustrating that a slight taller, yet slightly skinnier tire could cause this much of a hassle. The first one (silver - pic below) is a 2019 base. The second one (white - first pics I sent of truck that I’m having issues with) is a 2019 luxury. Maybe KDSS problem?

I keep getting told go with spacers. I’m just trying to delete rub and rake in front, and get rid of the lean… I just want it done correctly, even if that means swapping out a few components in the front.

Check out spec sheet - taking off my running boards tonight. I might do a Victory Blitz front, but may keep it simple.

Wondering what else I can do to slightly increase height in front to reduce rake and also stop rub with the KO3s.

Well if you don't plan on any extensive off roading and want to keep it cheap, simple and just a wee bit of lift to level it, I'd suggest spacers in the front coils.

Any suggestions on a brand and size - to level the front a bit and slightly improve the rake?

Sorry, can't help on that, I have full suspension upgrades. But I'm sure someone on here can direct you.

Another suggestion is to swap the front 5100s with 6112s - unsure if that would be a complete cure?

I am removing the running boards and eventually going with sliders.

Definitely a head scratcher… didn’t think this would be that difficult of an issue.
