Hi,
I can't believe I've been reading this list for years watching everyone
make the same mistake I just made! lol.
It's a 1991 Westy, standard transmission, 280,000 km on the Odomoter &
original engine, but unknown maintainence history on the rest of the
vehicle (except new alternator, new gas lines that I did).
That's a good idea about lifting the van to get a closer look. I'll look
around for chock like devices tomorrow morning when it gets light.
Cheers,
Steve W.
