Help! Differential bushing bolts mis-aligned - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Spacemane969 · 01-22-2018, 03:40 PM

Installing the whiteline differential mount in cradle bushings. Added the bottom vertical bushings and as I go to retighten the drivers bolt will not thread smoothly. Once I tighten it to max torque it still has about a 1/4 gap on the bottom washer. I don't know what to do..I've tried wiggling and repositioning the diff as much as I can but it doesn't solve anything. Is it possible the female threads are bent?
Thanks

Sounds like you have at this point crossthreaded it. Best to remove the bolt and bushings and run a tap through it nice and straight and start over.

Jesus. How bad could this be if I can't get the thread going? This might be a rookie mistake but I was unable to get all four corners on jack stands safely so I've been working with just the rear raised. Does that matter?

Wrench on things long enough and you will wreck a thread or two over the years. You're not the only one, especially on this subframe. Having only the rear raised may have hurt you in getting everything lined up, but it's possible to get it right with the car like that as well as it's possible to get it wrong even with everything lifted evenly.

I'm thinking it's mostly the weight of everything that is making the alignment impossible. I have a very cracked uneven driveway and the weight of the whole car could be leaning to the left or right side more than the other.

Thanks for your reply
