Rubbing still after BMC and 285's

[Mastr_chief]

Hello guys -

Finally jumped up to 285s after running my stock duelers. I'm still getting some rubbing by the body mount after doing a BMC. I'm running the current:

JBA UCAs
Bilstein 5100s
Dobinson springs
2" front, 1" back

285/70/17 Falken Wildpeak AT3W

See attached for where I'm rubbing. Any ideas on how to trim this? Or should I look at my alignment again?

I think your tires are too big.

 

[Mastr_chief]

No such thing.

What is your caster set at and what is your wheel width and offset?

With JBA's and a 2.5" lift I was able to get 5.1 and 5.5 degrees of caster and my k02 285s on 7.5 (-)16 offset wheels don't rub even with mud flaps still installed.

Unless you have an extremely low offset, wide wheel that's causing the issues, I would focus on getting an alignment from a shop that specializes in lifted vehicles and aligning for clearance. You should be able to get over 5 degrees with your set up which will give clearance (trim bumper of course) and also really improve the way it handles on road with regard to steering feel and overall tracking and stability.

I know this doesn't answer your question, just suggesting that perhaps there is a better way to approach this.

Pretty common. It's just plastic, so dremel or small reciprocating saw would work. Just keep cutting until it stops rubbing.

Edit: the plastic fender end cap also comes off. Behind it is part of the lower fender mounting bracket, if you're rubbing on that you can lightly bend it out the way or cut it off.

Stock TuRD rims?

I have an 06 Icon lifted running KO2 285x75x16 and they rubbed as expected.
Once I took it to the guys in my area ( I dont know if I can mention company names so I'll refrain) who work ONLY on off-road rigs, they did the BMC and the rub was gone.

Adding to what streetsyndicate said,

My question would be.

- Who did your BMC.? If they are Off Road Rig pros with 4R experiece in BMC's, then I'm sure they did a good job, but if you did the cut yourself, or didnt take it to a shop that specializes in Off Road Rigs and have 4R experiance, there may be a chance whoever did the cut didnt cut enough of an angle off.?

Find a Off Road shop and have them check it out

Good luck.

you need to cut that plastic fender cap, and sometimes the metal tab behind it (or bend it back).

Its pretty normal.

 

[Mastr_chief]

Ok, cut some of the plastic off and might have to bend the metal if it keeps rubbing with some flex.

Oh, and to answer a previous question, the wheels are SCS SR8, -10 offset.

 

[Snowtrooper]

As many have mentioned here, looks like the BMC was done correctly.

You might be able to just trim away that fender cap with a heavy duty box cutter. After that would be the pinched metal tab that can be bent in if necessary.

Not my photo, but pretty clean cut for someone else who’s search brings them here…

 

[Mastr_chief]

Perfect pic. That's pretty much what I ended up doing as well.

every vehicle is different. im running ray 10 -10 with spc uca caster all the way forward and no bmc.. no rubbing and im still have the stock flaps on.

Still Rubbing with BMC

Still rubbing on my body mount after bmc. 2014 SR5

2.5” lift
JBA UCA
285/70 R17 Falken Wildpeak
Wheels : 17x8.5 0mm offset, 4.75 backspacing
Caster 3.7

Beyond frustrated that I’m still dealing with this…just about want to get rid of the 4Runner for good.

"i created a problem and now i'm mad!" lol. :first:

 

[LeekT4R]

Trim it. Locate where its rubbing. And then trim it until it no longer rubs….its plastic.

"i created a problem and now i'm mad!" lol. :first:

Haha…very true! Just didn’t realize how much lifting and going to bigger tires would be such a combination lock. I researched the hell out of it before upgrading, but wound up with the typical answer for 4Runners…it depends. No guarantees.

Rim offset is hurting you.
Do you have any wheel spacers? Those do not help rubbing!
Lift also doesn’t help tire fitment, but that’s a different discussion.

I don’t have wheel spacers. What should my offset be? Unfortunately, I couldn’t go with less offset due to the loss of backspacing…uca manufacturer (Jba) recommends 4.75” or more to clear the the Uca. I considered more offset, but was under the impression that the increased radius of the turning wheels would create even more rubbing.

This is why I love the "will it rub?" question. Maybe? Maybe not? But, probably. They all do. There is no golden answer to it except to stay stock.
