I can’t tell the difference between the old sleeves and their sizes difference. Which sleeve goes in the front of the irs subframe bushing and which in the back?
I believe the larger diameter bold is for the forward mount. Just use the bolts as a guide if you forgot. One of them will be too big to pass through the sleeve.
Blkkbgt is correct. The one with the larger inner diameter goes in the front to fit a larger 9/16 bolt through. The stock bolts for the front subframe mount aren't that big and it is recommended to upgrade to a 9/16 grade 8 for increased strength.
Thank guys, didn’t think only one would fit. I did upgrade to 14mm front which barely fit the front sleeve but the back bolt/sleeve seems sloppy...much more play than I would have guessed.
