@TheMayoMachine and I went for a drive on Sunday and I experienced quite a bit of front end wander. At speed the front end would dance around between the lines and there was no movement at the steering wheel.
The first time I sensed this was when I took my Speedster to the wedding earlier this summer. After I noticed it I inspected the front end and I discovered a very, and I mean very, slight amount of play in both rotors. This likely occurred after I replaced the rotors, bearings, and pads when I replaced the master cylinder. I went ahead and tightened everything back up and thought that might fix it. I had been a few very short city speed drives and didn't notice any wandering so I thought I fixed it.
While out driving on Sunday I experienced it again and it was about the same. I got the front end up off the ground and inspected the beam ball joints, shock mounts, and the steering column. The only thing that had any noticeable movement was the steering column but it wasn't that much. I held tight to the front wheels and had my son turn the steering wheel. I noticed the column moved before the wheels so I loosened the jam nut on the sector screw and tightened it up. I've seen on other VW steering boxes another nut behind the box that also gets tightened but my steering box doesn't have that. The only adjustment I could make appeared to be the sector screw. I haven't lifted the tail end to see if anything is loose there yet but if the wandering continues I may have to. After that I went ahead and greased up the beam.
I'll take it out for another highway speed drive to check on this adjustment. While I was underneath the front end looking at everything I noticed a split in the rubber mount that connects the two halves of the steering column. Is that something that should be replaced immediately and if so what brands/types of replacements should I avoid?
