CMC for 2019 Tacomas? Did you need one?

[Lava road]

Owner of a 2019 Tacoma TRD LB with Leer camper..
My sons 2016 Tacoma TRD SB …2.0 lift Bilsteins 275/ 70R /17….Had no issues with tire rub , nor did he needed a CMC

My 2019 TacomaTRD, same size tires - 275/70R/17, w/ Bilstein 6112 (6/5), rear 5160, plus Icon Add-al-lift, SPC’s …I had lots of tire rub….I did a CMC, but still needs more trimming, schedule to go back to my mechanic for more cutting…this coming week…

Is there a difference between the 3gen Tacomas insider fenders space? Between 2016 ,2019 and up? I heard tire cutters ,33’s fits with No problems?

I beginning to think? Maybe I should of gone to a true 3-4 inch lifts,,,?
Aloha

Depends on wheel size, offset, tire. Since they are all different. Size tolerances. Are they Sports or O/R?
Assuming Sports.
30.6 to 32.2.
Some are just lucky. What is actually rubbing? Rubbing on the CMC or above on the fender?

 

[Mr. Nobody]

There is not a difference in the fender well design across the years. You said you're running SPC arms, what settings are they set on? That is step number one for you.

 

[Lava road]

My truck is a TRD - Off road, not sure is neg 12 off set? BFG KO2..

The rubbing is annoying…for sure…
Aloha

 

[Mr. Nobody]

Your offset doesn't help, but that's not what I asked.

You said you are running SPC upper control arms on your truck, correct? If so they are adjustable. They can be adjusted for upwards of 4° caster over stock to help combat the rubbing you describe. What are your control arms set at? And if you do not know you should start there in your troubleshooting.

See the file below or Google "SPC Tacoma instructions."

I just always ask about offset to see if it's a physical fitment issue. Some people just get their tires so far it'll rub just in the right spot. I'm dealing with it now.

For sure. Pushing the tires out further looks cool stance wise, but to far and it definitely can negatively effect the amount of rub.

Not sure what 4 degrees is…does this make the tires stick out more? Or does it moves the tire forward?

I notice my driver side wall to tires is 3 3/4 space ..passenger side just 3 1/ 4 space between wall and tires..I am right now at the mechanic shop..cutting the passenger side only…approx 1/2 inch ..maybe less ?

I will let you know of the results….But I am Not happy with the Bilstein 6112 , 5160 with icon add-a-lift…
The rubbing is horrible!

If I get to do this again? Maybe true 3-4 inch lift, and one size smaller tire?

Anyone else is experiencing this problem? After watching TacomaBreast Relocation Cab mount frame…this looks like a better answer to rubbing….Not a cheap MOD…$$$
Aloha

I just return after having 3/4 of inch more cut off ….still rubs on right turns, but only when it bounces…, I will look at in next week or so..to see if more needs to be cut off?

 

[kevjitzoo]

Did you get an aligntment done after installing the suspension?

 

[mgmyota]

You need an alignment done by someone who knows how to work with SPC control arms. Have them max the caster. You shouldn't need to cut that much with a 32" tire, even with -12 offset.

 

[Lava road]

Thank you for all the info’s ….I will contact a tire dealer on the Big island who does wheel alignment and they sell & install the SPC upper control arms…plus do lifts too….
I hope they will be can adjust the casters? ..move the tires forward..

I will let know you how it turns out?
Aloha

 

[Lava road]

My appointment was today …caster adjustment and wheel alignment….but the wheel alignment machine broke down…I need to re-schedule..

The wheel alignment Tech…said the can reset the casters to move the tire forward 1/2 x3/4 inches…
Often this is one way to center wheels in the tire well…SPC upper control arms.
Hope they will be able to solve my tire rub ..passenger side only

I did measure the spacing between the two tires, and driver side is wider on back space, vs passenger side is narrow.. ( wondering if came like this from factory? My mechanic did NOT touch the caster adjustment…

After your lift…good idea to re-measure spaces…?

Re-location kit Cab mount? Any ideas of the cost? After watching Tacoma Breast video on there cab relocation it looks expensive?
Aloha

 

[Lava road]

Ok ..the wheel alignment specialist did move my tire 1/2 inch forward…..now a new problem..the steering pulls to the right while driving, VERY Annoying!, (specialist did as told ,but never told me this is what is going to happen.

It did NOT solve the tire rubbing…looks like I have to go back and move it back 1/2 inch…I just spent $125.00…for nothing…Ah…
I have made another appointment to put it back to normal this Friday , Nov 5,

 

[Lava road]

Tire rubbing passenger side… I did cut as much as I can, my mechanic did a additional cutting …but cannot do anymore without chopping the cab mount off…

Do I need to buy a new relocation cab mount?
Maybe go back to a smaller tire?
Funny only the passenger side too!

Bilstein 6112 ,5160 with a add a lift….anyone else getting this problem…it is a 2019 TRD off road Long bed…-12 off set , 275/70r/17 bfgs

Help! Will putting the stock rims help? … yep that means 16 inch tires too or purchase factory stock 17 inch rims.

 

[nickyreno]

Just cmc it

 

[mgmyota]

get a pic of your alignment spec sheet and put it in this chat

 

[Lava road]

Hope this helps: left front chamber 1.1 degree. Caster 3.1. Toe 0.05
Right front Camber -O.1. Caster -1.2. Toe0.06
Front total toe= 0.11. Steer ahead = -0.01

Next question : would the TRD 16 inch stock rims fit the BFG’s 275/70r/16 ? And /or the 275/75r/16?
It seems looking at the passenger side if the tires/ rims were more under the fender? I might not rub the cmc? ,but would it rub the UPC or shocks? With the stock rims?
275/70/16 = 31.16 diameter
275/75//16= 32.24 diameter
275/70/17= 32.16 all above is approx …each brand may differ on specs..

I have some tire rubbing when I am making right turns only, and especially when I hit dips…annoying, but not as bad as before the first chop….highways NO problems, unless turning on a pot hole…

I am planning to go back to wheel alignment to move back that 1/2 inch…

 

[mgmyota]

Those numbers look like someone doesn't know how to align your truck in my opinion. Your caster is all over the place. Here is a link to a faq page on SPC's website. Maybe it will help a bit. https://www.spcalignment.com/partFAQ/25470_FAQ.pdf
I don't have these control arms so I can't help too much. Hopefully someone that knows more can chime in. But I would start by maxing your caster, and then set everything else to basically factory spec. You could also get ahold of SPC directly.

 

[mgmyota]

@Tyler Don't you know of a guy at mainline overland that's really good with these arms? Maybe there's a way to get our friend here and his mechanic in contact with him.

 

[Lava road]

Not sure how knowledgeable…but . They do sell a lot of these SPC upper control arms, and they do lots of lifts especially Tacoma trucks, popular here in Kona, Hawaii..
Bad thing is we have only three alignment shops..this side of the island…only two of them do lifts ,and install SPC uca…
The first shop did my alignment, the 2nd shop had to correct the first shop..lol.

I do on the east coast but @Lava road is in Hawaii. Or did you mean over the phone?

 

[mgmyota]

Yeah over the phone. Maybe he could help walk them into getting it perfect. Just a thought if all else fails

@Lava road - let me see if I can contact them about this.

Also, everyone with this issue should try showing this video to the alignment guy. If the alignment guy doesn’t “get it” after seeing the video, don’t even bother with him.

Great Info Tyler !

 

[cocodataco]

With only 3 alignment shops on the island, sounds like you got your work cut out for you. Sharing my most recent spec sheet for reference here in CA.

I’m running 295/70r17 on 17x9 -38 offset. 2.75” lift up front. ICON tubular delta joint and with 3.5 degrees of caster I don’t rub full lock. Different story while wheeling, I rub mostly fender plastic but have yet to feel the need to remove ‘em.

But in your case with SPC UCAs you should get 4degrees, I have a buddy here with spcs and same wheel/tire setup as me with no rub full lock.

Looks like my truck for some reason, with CMC still rubs on the passenger side only…my son’s 2016 same lift ..NO. Problems..
And it seems other Tacoma owners…seems to have NO issues after the CMC …

Note I will move my passenger tire back 1/2 inch due to steering pulling right (annoying)…have to put pressure to keep straight and it did NOT solve my tire rub..

Will a Cab re- location kit move the bolt back too? I need to cut into cab mount bolt area , cut maybe 1/2 - 1 inch off… meaning the bolt space needs to be gone?
Help

That's because your right side caster was -1.2 and your left side was +3.1. Your caster should not be negative. @cocodataco alignment sheet is how it should look when done correctly.

 

[Lava road]

I Just talk to the alignment etc…he will move the driver side forward to match and eliminate steering wheel pull…
Let you know after I take it home…
6 months warranty..NO charge and I can take it back up to six months.. which I will as the lift settles…April, 2022….
Hope all goes well… I may have to leave with the tire rubbing ( right turn bumps) …till I can find ways to solve this…
Aloha

 

[Lava road]

The alignment shop move the driver side forward…all green bars on the specs…
Drives nicely ..no steering wheel pulling…!
Usually when driving down the hill on our coffee land road, I will feel some rubbing…so far NONE..
Now I will need to test it more…rougher spots..
Did moving the driver forward by 1/2 inch makes a difference on the passenger side from NOT rubbing? Um?
Let you know after further testing…
Thank you for everyone’s help…MAHOLO’s

Caster will move the wheel forward away from the cabin mount and fender liner.
They should be even. A lot of rubbing issues are remedied from bumping caster up.

Did you take a look at what you were rubbing on?
