UMI torque arm - HELP!
Hey guys, got a little problem here.
I recently had the UMI adjustable torque arm installed. Driving around, I noticed thuds when I was starting to accelerate. I happened to notice the poly torque arm mount lying on the road behind me. Picked it up, took the car home and jacked it up to see the clam shell is open.
I noticed there are two holes at the top of the clam shell where I assume a bolt/bolts must go. Problem is that they are missing.
I need to know what hardware is needed for the clamshell???? The top bolt/bolts and/or nuts that are used....

Re: UMI torque arm - HELP!
Your torque arm was dragging and/or disconnected?

Re: UMI torque arm - HELP!
It was disconnected at the front, so it wasn`t dragging. The front was knocking against the transmission. I went under the car again this morning with a light this time. It`s just the one bolt that`s missing. The one that goes through both pcs of the clamshell and into the trans. There`s no hole on the other side of the trans, so hopefully I can guess the pitch and length needed. Time to bring out the box o spare bolts.

Re: UMI torque arm - HELP!
Hmm.. I would contact the guys at UMI and get the right bolt for this.. Don't want to risk that falling out or causing damage to it or the tranny. When I installed mine I purchased new hardware to go along with it too, did you re-use your old stuff?

I bought the new hardware for the rear, but not the front.

Re: UMI torque arm - HELP!
That sounds like the old hardware might have been just broken or maybe not the right size or who knows. New hardware can be bought for cheap at your nearest hardware store, just make sure you buy the right size. I'm not sure what it is but if you call UMI up they will be able to provide that info for you.

That bolt threads into the transmission.
Stock, it was 10mm x whatever the std thread is for that size; probably 1.5mm but I'm not sure. Probably around 40mm long. Has a washer head. Prolly find a perfect identical replacement one hanging on a card at the parts store.
