Broken Differential mount blues...Again
 

yep after about 3months of driving my FC with a mazdaspeed competition mount it hit the bucket, not sure if it has to do with any of the following, bad rear tires, cold days, fluid needs changed. Not sure I want to weld it together but wouldn't the road vibration be bad on a daily driver?

I think welding it changes the suspension geometry, so that may be a "no-no."

OKay well I just got back from the auto skills center on base, and left my car there....well it turns out my differntial mount is in fine condition, it was the bracket on the sub frame that busted off....I took the whole subframe off and took it to a welding shop, I got some washers and the broken piece welded back on...should I just put it back on or go for a new/used subframe....also anyone else have this phenomenom? I was like wtf when I saw the mount was okay then I saw the cracks in the metal bracket...just a follow up post any questions or replys or anything...diff fliud is still nice and translucent well with an orangish tint

ya, competition mounts can do hell to parts on the car, thats why they usually state to only use them on the track since they can crack parts etc
