UPDATE - 7 May 2015: This thread was crossposted to 5th Gen T4Rs. Please post any replies or follow ups to that thread. Also, this issue has been resolved by the shop since the original post was shared. Here's how they fixed it.

=================================

Begin original post from 1 May 2015:

Note: I did a search on “body mount chop” and other related phrases before posting.

I’m hoping to get some advice from someone with experience in installing lifts, chopping body mounts, and making frame modifications.

I took my 2012 4Runner (SR5) to a local shop for a lift/level, new tires, wheels, shocks, etc. During the initial consultation, they said wheel spacers would not be required. While the installation was occurring, they called me and said the wheels were rubbing against the calipers and that we would need to install spacers to clear them. They agreed not to charge me for the spacers. Parts installed included:


I returned to the shop at 5pm and was informed they were almost done with the installation. The Salesman said, “They just need to do some minor trimming and take it for a test drive.”

They were finished about an hour later and the Salesman walked me out to my vehicle. He said, “Now Doug, I need to let you know something. They had to do some minor trimming to keep the tires from rubbing. Most people wouldn’t even know it was there but it’s important that you know where it is.” He pointed to some trimming that was done behind the front bumper and then he pointed to the trimming done behind the front tire. He said, “They removed a very small amount of metal and then repainted it black. It’s barely noticeable at all.” I looked at it for a few seconds, trying to remember what it looked like before the trimming was done. I told him that the main thing I was concerned about was safety and function. I said, “That’s fine so long as the frame hasn’t been compromised in any way. He replied, “Not at all. They only removed a few centimeters of metal.”

The metal trimming surprised me a bit. I didn’t realize they were going to do that. FWIW, I paid for the “Xtreme Plus Warranty “ (3/36).

Is this modification safe? Did they do it right? Is there anything I need to be worried about? Thanks in advance for any information or advice you can offer.

Doug

I wouldn't let them give it back to me like that. I'd tell the manager you wanted a sheet of steel welded over the opening. The thinness of that metal next to the bushing is way too much for my liking. They also should have asked you first.
 
that's a rough install...and as the last poster said, they should have called before cutting into any part of the frame on a 30k SUV. If anything, they need to weld some 1/8 plate over the opening and box it in. Toyota engineers build the frame mounts a certain way for structural rigidity, and that's been compromised.
 
First, they should have asked permission as others have said already. No excuses.
Second, many of us don't weld on a plate after chopping it to fit larger tires. You aren't compromising integrity because the body mount is inboard of the chop, closer to the frame. I and many others have wheeled the hell out of our trucks and I've never heard of any failure yet, FJ's and Tacoma's included as they have the exact same issue. So, to make it fancy looking sure, you can weld a cover plate over it. Would I bother, no not really. That mount is a boxed in tank of a mount! Wayyyyy overkill. That's why it gets in the way. ;)
Also, mine if cut much more than that as I am running 35" tires on my 4th gen.
