Hey- I just got a 87 non-turbo rx7. Its a great car and all, but its got one little problem; when i start going, i'll shift from 1-2, 2-3, and so on. When I shift, as soon as I let the clutch out a little, the rear end kind of 'pops up'. I have been told that its the rear end bushings, but I really dont know. Someone PLEASE give me some info on how to fix this!!

And I have one more question-
what does FC mean?? Sorry, but I'm new to Mazda.

get new bushings?

 

FC is tha chassis designation. 1986-1991 RX7s are FCs.

It sounds like your rear diff mount is busted. Do a search on that and you will have a ton of info.

thx about tha FC thing andrew
but i've lo0ked at a few other threads now
and i think its the bushings now.
Because other people with the
problem say its the bushings.

one more question...
this may sound stupid,
but where would the bushings be?
i know they're in the rear end somewhere
but exactly where?

lol thanks a lot you guys

 

the rear diff mounts or mounts are most definitely busted.... same problem with my homies car

 

If it's loud it's the front diff mount... If it's not so loud, and the vibration continues, it's the u-joints on the driveshaft... Sounds to me like everyone pretty much nailed it though... Search for "welded subframe" and you'll find some good info on how to fix it up...

You need to get a service manual in the worst way.
