    Question What hardware to replace when installing LSD and subframe bushings?

    Ok Folks,


    I am preparing a shopping list of parts that I will need for the complete upgrade to LSD, diff bushings and rear subframe bushings. For those who have done this exercise already please share your experience here.


    Please, identify which fasteners and other components MUST be replaced during LSD and rear subframe removal:

    3. Subframe:

    Thank you in advance and I apologize for the size of the image. I took direct screenshots of realoem.com

    Lockdown diff and brand new bolts for axles and the pumpkin. It's also a good time to swap to M3 sway bars and upper arms if you're dropping the subframe.

    The 26117567770 is mandatory, nothing else is needed (that I know of). Also make sure that the shop has a thin wrench for this nut, if they don't they can make one by grinding a regular wrench. But also get the axle screws.

    Yeah it's recommended that you replace the insert nut for the driveshaft and the axle bolts. If you're doing the diff, might as well do the DEFIV lockdown kit as well; it's just good timing. If you want to go further, it would also be a good time to replace the subframe bushings.

    If you plan on doing the subframe bushings yourself, rent the removal tool from VAC. It was worth its weight in gold, and made the job cake. I was able to lower the subframe enough to swap the bushings and install the M3 sway bar without disconnecting the driveshaft. I only had to disconnect the brake lines, then bleed the brakes after the install.

    So is this the "Repair Kit Insert Nut" (P/N 26117567770) shown in the above diagram?

    That's the plan. I will be getting the LSD from them anyway and I'll just rent the bushings removal kit as well.

    Its too expensive for me to justify the price. My car will never see a drag strip or hard launches. If I wanted a sledge hammer for burnouts, I would have gone with American muscle Click here to enlarge.

    I really think it's priced well and seems to be more than just for the strip, plants the rear.
