No issues with subframe wear. I would say the Black, street version is more than enough. The harder you go (RR Red or Kein) it just gets worse. I believe Rafi has the Black mount on his car and reported some NVH. That said, I've logged about 8 total hours behind the wheel of his car to date and I don't find it bad at all. There's a little road feel through the wheel at low speeds. The car is loud and I don't hear any extra noise because of that.

Thank you @lobuxracer for mentioning this sound in another thread as it lead me to find this larger thread on the subject. I have this same sound right now and have ordered all the parts to replace it. Thanks everyone for all the part numbers in here.

 

Replaced my mount a couple of weeks ago. Expected at 158k miles for it to be worse off.

 

**UPDATE**

So I finally replaced the transmission mount and the noise is 90% gone. The mechanic didn't jack up the transmission while replacing the mount and the brace that connects with it, is that a reason its not 100% gone?

Should I be worried? the old mount was about the same height as the new OEM one.

Thank you

 

The bracket (shown below referenced by Yellow arrows), is only used with the IS F V8. not IS with V6.

 

I was under the car working on installing the driveshaft so I replaced the tranny mount (OEM) and the bushing at the front of the linkage. The mount wasn’t compressed as other reported but felt little bit hardened.

As far as the bushing, it wasn’t deteriorated yet, but very hard and dry so good decision to tackle it. Thank you for the part list.



It is just one nut to be removed and then it gets easy. It comes down for a great access. If you ever under the car, easy task.

Parts Diagram

 

^^^ just did the bushing, sleeve and the pin.

 

Understood, thank you for the follow up!
Is the "sleeve" part 90560-08091- Spacer for transmission control rod (referenced as 35569C in parts diagram above), shon at bottom in photo below; ?

 

yes it is, you can actually use the old one, those do not deteriorate

 

Thank you again for the follow up!

Browsed the discussion to better understand where the linkage located, to perform the parts change as well (IS350). I understand this to be discussion for IS F vehicles however, interested in knowing if the the link assembly would be located in similarb location underneath the IS350 as with the IS F?
Photo 1- front link assembly? (provided by Joe Z Reply # 62)Joe Z – Reply # 62 - I swapped the grommet & bushing today, putting the F back on the 2 front jack stands.. It was a tight space to work in, but got some lessons learned.. Have the right tools and make sure the car is safely high enough.. Working on a lift would have made this swap much easier..

I'd like to see the rubber bushings in polyurethane.

 

Interesting inquiry!!

Perhaps FIGS Engineering may be able to assist with manufacturing a kit??????

 

I wonder if there would be enough demand for a production run.

 

For the shifter? Delrin would be a much better choice.
