I have a 2000 S2000 with a busted differential mount. How bad is it to drive on it for a while? Is this something that should be replaced sooner than later or is it something that can wait until there is other work being done in the differential area?

 

you diff will move around, soon the seals will leak and you will run out of oil

 

E mounts can be bought cheap used. I know I have at least three sets I would love to sell.

 

Cut bothe ends off, leaving the center webbing, and clean it out. Use window weld to fill it. Works great.

 

So this is something I should get fixed and not something I can ignore?

 

Yes, an easy fix that if ignored will lead to a very expensive fix.

 

Absolutely. As a matter of fact, one of my mounts busted and it leaked fluid. When i would take turns it would hit the exhaust. I went and bought the EVS diff collars and i just replaced them last night. There is ZERO movements now and i highly recommend them.

THIS!!!

 

I am going to get this fixed. Isn't it the rear drivers side (left) mount that always goes out?
What parts would I need?

is it just the rubber part I need?

 

#2 is passenger, #3 is driver. All you need is the mount itself.
