I am replacing the shocks in my 93. I have not looked yet to see if I need new rear strut mounts, but I went online, and rockauto and advance auto, only list rear strut mounts for AWD applications. I got the part number from alldata for my car and there seems to be a different part for left and right, and when I looked it up, it specified that it was a part for 2WD.

So, am I correct to assume that the AWD and 2WD parts are different? And does it sound like I need to go to dealer?

The only reason I think the strut mount might be bad, is because there is this vibration from the rear left when I stop (brakes are good). It is either the strut or the mount. Has anyone else experienced this?

Thanks

For future reference. The part numbers for the rear strut mounts are as follows:

Right: 20370AA220
Left: 20370AA230

I think this applies for 2WD 92-94 Impreza and Legacy,

That seems really weird to me that the fwd would have a different mount for rh and lh, while the awd has the same on either side.

I seem to remember reading, somewhere, that during a swap the awd strut assembly simply bolted in, weather or not any modifications had to be made I don't recall.

I know that there are some folks around here who have done the fwd to awd swap, maybe one or more of them will chime in and clear up this confusion.
