idk what the problem is really.. but i can start up the 88 turboII rx7.....but when i put in 1st.. and i start to roll.... i can feel and hear a loud popping sound commin from the rear.. then i put it in 2nd, and pops again...i have no clue what it is..can someone pm me and lemme know what it may be?

 

Why pm? Just post it in the thread.

I have the same problem.

 

Check your u-joints and diff mounts.

 

sounds like the front differential mount, if it pops everytime u shift

 

Yep, diff mounts. I once had a popping noise in my FD though due to a worn control arm bushing. It popped on shifts and bumps.

 

I doubt its the driveshaft(u-joints), more than likely the front differential mount.
