Well, after a hellish day yesterday, got new rear Sensatracks installed. Bloody horrible job. The bottom two bolts are an absolute nightmare. I guess that good old Canadian rust has done its magic over the course of the last 11 years. MAN, was that ever a bugger! Oh, and if anyone is doing a Ninety Eight, probably Park Avenue too, the back seat has to come out, but the speakers don't have to. Just ignore what the useless Haynes manual says.
Oh, and what a difference. Still have ELC issues, but at least it doesn't bounce continually now. Only problem is, now that the rear struts are nice and tight, the front is feeling a little loose....
Anyhow, big thumbs up for the Sensatracks. Thanks, guys, for talking me into them!
