I just took the car to have tires and wheels all balanced today as well as get an alignment. The vibration is still present.
I am 100% sure its in the driveline (behind trans) bc when im going along, it doesnt matter what gear im in as long as its about 70mph. If i let off the gas or push the clutch in, it gets worse. I think this is because there is no tension to hold WHATEVER is loose tight.
The car has been lowered.. and Im REALLY REALLY trying to avoid buying those control arms.. im in high school and 200 bucks is not easy to come up with, although I did take it to the shop today it was for a good cause. I did get lifetime alignment an my dad said he would pay for the balance. It does ride smoother at 65, but thats not the vibration i was chasing.
Yes i marked my driveshaft and yokes when replacing u joints- the vibration was present even before doing that. I replaced them with Duralast gold U joints and it helped...some. After replacing my TS bushing the vibration improved even more but still prominent @75. I WANT IT SMOOTH ALL THE WAY UP!
I have read that people lower mustangs ALL DAY LONG and dont have any problems for thousands of miles. Why should this be any different? my UPPER control arms are factory, but the lower ones are from BBK. However, I REALLY dont think that they are the cause. IF my pinion angle is off, is there ANY other way to fix it than those damn control arms? Cuz I need new tires too :/ They balance out fine, no vibration, but im down to the wear bars in the back.
Thanks for all the suggestions, but I am still unsure of where to go from here. Getting the rear end checked out is a really big deal, as I dont have much experience in that area. The driveshaft ran FINE in my ol vert, so i dont think its that. Im guessin yall are right- either pinion angle or a bearing (dear god please no) It drives me insane not being able to drive a babe around without desperately trying to hide the vibration!!! hahaha
OH! and PS- the tranny mount is FINE. Ive had the trans out myself a few times to do the flywheel resurface and press plate resurface- damn centerforce clutch! Its still outta balance... very slightly. How irritating.
