[Street Fighter]

I have a bad whop,whop,whop sound coming from my TA It seems to be in the rear of the car sone where, but I can't find out where. I have had the tires checked and balanced.I have checked the trans mount.Replaced front balancer,and checked converter.What can it be?any help will be helpful.

do you have any suspension mods? axle bearings maybe?

[Street Fighter]

I found the problem.It was the converter.Some how the balance weight fell off.I am trying to find the # to B&M to see if they will rebalance it.do anybody know it?

Is it a constant noise or does it only occurr once you hit 2200/2300 rpms?

I had a strange type noise turned out to be the pinion angle needed to be adjusted.

Has something to do with the U-joints and how they are suppose to rotate.
