Sliding door

86 Westy
Our lower track is filthy and looks to have accumulated a large amount of debris that looks to have clung to grease(?) on this track
I am really not sure what to do... Do I just clean it up as best I can and apply more grease? Won't this lead to the same problem?
Should I take the door right off?
Clean up all three tracks?
What do I apply to each track? Plain old grease (like out of a grease gun?)
Any help is much appreciated.

The sliding door was not one of VW's shining engineering feats in terms of maintenance. It seems you have to remove the left headlight to get to anything!
Keeping the track clean is important, but more important is keeping the slide rollers clean yet lubricated. The upper is usually pretty straight-forward as it is protected by the gasket seal when the door is closed. The lower gets far more debris as it is only protected by the door overhang, no seal.
A third area that needs cleaning & lube is the rear sliding door pivot arm & roller. You pretty much have to remove the body slide shroud (Bentley 58.11) to get to it. I wouldn't remove the door unless absolutely necessary.
Upper track is easy, just wipe clean, using a rag on a stick or Q-tip type rig to reach the nooks & crannies. I prefer a polyethylene grease as it's non-staining with good retention characteristics. Comes in a tube and is a semi-transparent amber color (Ford P/N DOAZ-19584-AA for one). For lubing the roller, I prefer one of the sprays that turns to a grease such as Lubri-Molly's Hi-Tack Lube P/N 2013 or 3M's version P/N 08878. These spray like a WD-40 oil and flow, then dry & work like a grease.
Ditto the bottom, but you may have to wash it out with one of the degreasers or spray engine cleaners (Solder Seal's Gunk or one of the foaming ones). Rinse thoroughly and rewax external paint surfaces. This will also wash out lube in the roller so has to be relubricated. That roller is at least easier to remove and do right. I still prefer lubing the track with polyethylene because I'd rather fight the dirt than replace/repair a worn track. In reality, it's a once-a-year job, if that often.
The rear pivot arm & track require the same care and is even harder to get a spray tip into, but has to be done. It doesn't get as much debris as the lower.
Door alignment and adjustment is done with the lower roller guide assembly. Besides gasket leaks, the electric power door lock terminal (if equipped) can lose contact if not properly aligned.

The Ford PN is -- according to our local dealer -- now obsolete and Ford has not offered any replacement.
It has been suggested that I purchase a teflon base instead.
Thanks for your list.

3M has a new silicone paste that ought to be as good, and I've used the silicone sticks on other sliding tracks. I'm not super-impressed with Teflon because it has to be chemically bonded to the metal surface to work so topical applications aren't much of an improvement over regular lubes.
I saw a tube of polyethylene under an unrecognized brand at a local store just the other day so it's probably a matter of searching the auto & hardware stores and opening a few tubes. Polyethylene is usually amber and semi-transparent without a petroleum odor.
Sliding door latch

Having problem with slide/latch assy on '73 Westy since re-installing (body work). hard to latch & doesn't pop out when opening. Bently not too helpful. Any one have any experience with this?
Capt. Mike Moderator Member # 11 posted 10-20-2000 08:03 AM
I don't know how you can say the Bentley isn't helpful. There are detailed directions on adjusting the door's upper & lower rollers, striker plate, retainer latch and locking plate in Section 1-5.12.
Obviously, a new weatherstrip can cause some of these same problems if it was not a correct OE, or installed correctly.
Last, nothing in the Bentley can correct lousy body work. Re-examine your body work to see if the outside runner rail, frames, jambs, and sliding rails all meet OE specs and are correctly aligned. It's also possible they didn't correct something that should have been, and now you have a fit problem between new and old body points.

A related question (I also saw this same question asked in the archives, but the response didn't fit my situation): The sliding door on my '84 Westy sticks badly, The latch and handles on both inside and outside work fine, but opening the door requires a little "hip check" outward from the inside. The problem seems to be sticking or suction from the seals, NOT one resulting from the latch mechanism. Any ideas?
Capt. Mike Moderator Member # 11 posted 12-27-2000 01:10 PM
I tend to believe it's an adjustment problem. The pop-out feature is a result of the articulated center hinge assembly. It's a complex set of dynamics, but basically the wedge of the stricker plate puts a constant pressure outward on the door. When the latch is released, it tries to slide back down the wedge. If the center hinge is operating correctly, this will make the door go over-center and then pop on out.
Start by inspecting your striker plate. Has it lost the little white plastic striker surface? This is a common malady on all VW strikers and will take away both wedge effect & add friction that the release may not overcome. Plus play with it's adjustment both in & out and up & down.
There is a tension spring and operating cam in the sliding door center hinge and an operating cam. If either has been damaged or worn, it would affect the hinges ability to cam out. You can overhaul the hinge assembly -- diagram in the Bentley Section 58.8. It is lubricated (Section 58.9), right?
Also check your front adjustment because that has an effect on the rear pop-out dynamics. The front should help in camming the door out due to it's rail countour. If it's holding the door either too far forward or aft, it could affect the rear tension.
I wouldn't plan on it being suction -- the Vanagon has a natural exhaust so doesn't have the drum-tight state of the earlies Beetles. If that was it, it would pop open freely with a window cracked.
New gaskets can be too thick, hard or not seated correctly, creating additional pressure. Common on aftermarket seals that aren't OEM. Sorry, no cure there except to get a proper fitting OE or OEM seal.
Sliding door won't latch

Searched the archives....Read the Bentley. 87 Westy
There are some good instructions in the Bentleys for adjusting the sliding door, but there are a couple of terms that don't seem to be defined. These terms are critical to understanding the instructions. They talk about the "B-pillar" and the "C-pillar". What are these? (page 58.11).
None of the items in the troubleshooting section exactly match my problem anyway. Basically my side door will occassionally fly open when going up hill (gravity assist), or at best it will only latch on the back latch. The front of the door doesn't want to latch so the door remains open a crack in the front with air and road noise coming through.
I inspected top, bottom, and both sides of door and door opening for obstructions and I always keep the tracks clean. All the screws are tight and the vehicle has never been in an accident. Any suggestions would be appreciated.

B-pillar is the one closest to the front door, C is at the rear of the sliding door. (A is the front door hinge pillar.)
The front of the door doesn't "latch" per se. The tooth on B-pillar engages the striker on the leading door edge to become a fulcrum point for the latching to be done by the rear cam and latch assembly. So the door only 'latches' in the rear with any positive means.
Sliding open with being released indicates a problem with the latch or latch adjustment. Is your door camming in on the hinge link completely? This can also occur if the door hieght is off because the latch and striker pin are no longer lined up correctly.

In the past few weeks my sliding door has started to open for no reason. While looking at the door i have noticed that the latch seems to be worn out. I am unable to locate a part number for a latch that I can purchase. Could it be the latch wearing out or is there another trick to my problem.
