When I have 4 people in the car & I go in reverse while turning I get a grinding in the back end. Could this be the Differential?

If it only does it when you have 4 people in it then it could be load/weight related. Do you have symptoms when alone in the car?

 

How much mileage? Could be worn suspension parts.

No, it is not your differential.

I agree with suzam - how many miles?

Any rust? Are you in the northeast/rust area?

 

is this an impreza or legacy brighton - i don't think there is such a thing as an impreza brighton.

do you know if it has rear disc or drums (late 90's brightons had rear drums, and impreza OBS did as well).

Backing plates can rub...maybe they're touching under load?

Axle on exhaust?

suspension is rubbing something.

300,000km it is an Impreza Brighton (station wagon) 2.2l , Windsor Ont Canada @Suzam no problems when I ma in the car by myself or 2 people. actually mine is exactly like this one http://saintjohn.bizcaf.ca/2000_Subaru_Impreza_Brighton_Sport_Wagon__Saint_John_bizcafAd_123722.dhtml

do you know if it's central or outer (left, right, both?)?

 

have someone sit in the rear compartment listen to narrow down the location. center, left, right, etc?

 

gotcha, they were called impreza outback sports here, didn't know you were in another country. brighton is a legacy only trim here.

Will do once I get my heads back on. Thanks!
