Fixing Rear End Sag

Front tires were wearing horribly on outside edge. I adjusted the lean as much as possible to get them as close to vertical as I could but still had wear problems. The tire gut told me after my last new tires that I had broken springs in the rear and that I would not be able to get the alignment right until I got new springs. I jacked up the van and looked at the springs. They were not broken but the spring perch on the trailing arm was mashed in and the bump stops were gone.
Pretty bummed at this point but decide to try to make a replacement spring perch patch based on one I saw on the samba.
I used two layers of 16 guage sheet metal from Home Depot - about an eight inch and as thick as I could cut with a jig saw. I cut one disc slightly larger than the other and welded the two together. The difference in diameter gave me a lap joint where I could run a bead and practice my sorry welding skills. For the bump stop I used a 1 1/2" plumbing coupling fitting. I was able to cut the top off of the old bump stops and welded those onto the coupling. With the patch perches done, I welded those onto the trailing arms. You will need a grinder with a twisted wire wheel attachment to get down to good bare metal for the welding.

Gas Cap Alternative from Mercedes for VW

I was at Wawa the other night getting a sub and some gasoline when a couple in a convertable VW modified into a porsche speedster pull in to the pump next to me. We started talking and looking at engines. I finally went in to pick up my sub, hopped in the van and merrily drove away, losing another gas cap but not pulling the hose off the pump.
Saturday morning, I am at Crazy Ray's on route 1 in Jessup, Maryland, an awesome pick and pull junk yard, with my shopping list which included a gas cap. None of the VW caps looked right so I pulled this cap off an 80's mercedes diesel D300. It looks like the the same cap as the 80's gasoline mercedes.
It fits nice and tight.
So, next time you are in the junkyard, pick a spae cap off a mid 80's MB.
installed, snugs right up
