I noted louder noise when switched to neutral while driving on my 85 GS.
Eventually I am going to open up and change if the differential drive ring, if worn out with play. Few years ago I have changed the entire differential unit to my other 84gs to look like gsl-se.

Kindly advise if I can improvise my new GS differential with lsd ( want to keep this housing no rust at all on 8.5k mile differential housing)
Or swap take the power from Turbo II setup

Thank you.

 

Maybe it's just the u-joints on the driveshaft?

The GSL-SE rear will handle the power from a TII swap. Once you start upgrading the turbo, you're still fine to about 350HP as long as you don't abuse it with things like wheel hop.

 

Thank you for the quick reply. BTW What u mean by wheel hop. bigger size wheels like 17 -20 !!

 

I mean wheel hop. On hard launches, if the wheels hop up and down against the pavement, they transmit huge shock load to the drivetrain.

 

Thank you, I am not that crazy to bump or skid wheels, just a front footer on streets. Time to find find another gsl-se rear and front swap. Thanks again.

 

BTW: Can some one explain the symptoms on when the U-Joint is an issue. I still could not figure out if this is a u-joint or differential ring, bearings.it still clunking , jerking while on coasting or slow freewheeling.

 

I had the same problem when I backed up slowly. Turns out the pillowballs were bad, I'm not sure if your rear suspension has them.

 

Thanks for the quick reply, but no pillowballs for 1st Gen FB. any more advice for me to try out !!

 

Can any one help suggest, if these wheel go for 85 Rx7 GS
