Help! Vibration pissing me off
 

Hi Guys and Girls,

I haven't posted here in a long time, but I need some help. I have this vibration coming from what feels like the rear of the car. I cannot isolate it. I had it aligned and balanced last week... but to no avail. The car is lowered 2.5" and has 18" cobra r's. I bought new tires not long ago and that's when I first noticed it. I had 265/40's on it before and they were just too big and then I put 245/45's on it. I have noticed a vibration ever since. I was told it was not the tires after I had them checked twice. WTF? I have heard that I need to check my tranny mount (I have an automatic) and my U-joints. What else should I be looking for and what should I be looking for when I check my mount and U-joints? THanks a ton.

Have you had any rear end work done too it? or maybe the driveshaft needs to be balanced?

I long time ago I had the 4:10's installed. It was balanced then and I had no probs with it. I'm pretty sure that this is something different.

check to see if you broke your rear swaybar. I did that one time and it was vibrating bad.

i would check the u joints, tranny mount, and the rear sway bar is possible, it happened to me once.

Got up under it today... the tranny mount is completely hosed.

In case why you are wondering why I moved your thread, https://mustangboards.com/modular-4-...4-6l-tech.html

No problem. Thats why I was lettin you know why I moved it instead of just moving it and you not realizing why. :beerchug:
