Previous owner told me it needs work but I would like to get a new one... It's a 06' Evo 9 MR its my daily driver, also the tarmac, snow, and gravel lights are all on after 30 seconds from turning on the car... In the future I would like to replace the rear sub frame with something like a magnus subframe... Because it's a little rusty... Thanks guys.

 

The rear subframes are aluminum. The rust parts you're seeing are the diff mounts, The tarmac/gravel/snow lights being on means there is a problem with the ACD, not the rear diff. It could be a bad ABS wheel speed sensor, it would be a bad ACD pump, a bad sensor inside the ACD pump, or it could be as simple as someone didn't properly bleed the ACD hydraulic system and it needs to bled.

 

this is why you always PPI (****ty rhyming is ****ty)

 

The better question is what is the closest reputable shop to get your evo sorted out. What part of Florida are you in?
