Clunking noise on deceleration after TA install I installed a UMI adjustable torque arm (transmission mount w/ poly bushing)a few weekends ago and it seems as though as long as the driveline is loaded I have no noise. However upon low speed deceleration where the driveline is not loaded I can hear what appear to be clunking noises coming from the torque arm.
Is this normal or is this noise something I need to check out. All bolts and nuts were tightly secured on install. Maybe re-check these?

Hello,
Check the two 5/8" bolts that attach the torque arm to the rear bracket, these are the bolts you loosen to adjust pinion angle. The bolts run through (2) pieces of 3/8" thick steel plate and it takes a lot of pressure to compress these plates. If the plates are not compressed enough the torque arm will shift slightly causing a bang.. Check this out... if you have additional questions please ask.
Thanks!

) and everything is now quiet and solid. I could see a small gap when I pulled the TA off the car. Thanks Ryan! Happy w/ the product! Also put a STB on the car and that is a nice piece as well!

Just thought I would throw an update in here. I tightened those bolts (had to take the TA of the car) and everything is now quiet and solid. I could see a small gap when I pulled the TA off the car. Thanks Ryan! Happy w/ the product! Also put a STB on the car and that is a nice piece as well!

I've been havin' the same problem with my TA mount. I've torqued to 130 pounds though and still the noise is back. Granted mine is BMR (sorry UMI, I needed one in a hurry and all I could find local was BMR...I do have UMI hardwar kit though, SFCs, and double adjustable PHB) but I think it's the same problem with the plates being so thick.
My question is when I've torqued, it's always been on a lift that had the suspension unloaded, would I get better results on a drive on lift?
Any other suggestions to get this right would be fantastic...it's driving me crazy!

Is it mounted on a factory or aftermarket rear end?
The rear suspension being loaded or unloaded should not make a difference.
