So I've done some searching and have found no answers. I've had an 83 wagon for just about 2 years. For the first year and a half I felt like I was driving a bucking bronco.

I finally broke down and replaced my accumulators...should've done at earlier, it's been riding so nice!
But here's my issue... Even with the bad accumulators the ride height was close to level, but every couple months it'll decide to drop it's rear end. I've found that whatever the problem is it remedies itself after a couple days. I thought fixing the accumulators might stop this...but the car decided to do it again and I'm tired of driving around looking like my bumper is dragging every couple months. I just changed the filter and did a fluid flush with the new accumulators. I don't see any leaks around the valve. So could anyone direct me in the right direction?
And while I'm at it...since it's gotten cold here, I have a belt that like to squeal. It's worst when I turn the heater on and will stop when I let off the accelerator. I haven't got to look at it yet, but thought I'd throw that put there too.
Thanks for the help you guys are! I wouldn't have the car if it weren't for this place.
