71-74 Jav Window guide Bushings "No More Wobble"

billd wrote: I guess it's the guides that are missing in mine - I thought all this talk was about those since that's why my windows wobble around and won't roll up and down without holding them as they tip fore and aft. But it seems that there's nothing plastic/nylon in my doors at all. Geesh so there's other parts it needs.  And no, people keep saying to go to AMARK for those guides - he's not had any for a while. I need everything window related (including tinted glass) - the nylon guides and now I see there's bushings, too? That sure looks different than my 73 door inside but maybe that's because so much is wrong in there.

        I have an assortment of door parts in my barn if I can help and I have it I will send you what you need. I will make the new bushings in Feb. if you are interested.

It's been a long time since I checked adjustments on window guides. Isn't the guide rod round bushing to have some slop (thin ring for a reason), as the rod has adjustment at the bottom of the door frame, for tilt. It would explain the bottom square bushings as to keep the rod stable after adjustment. Maybe once I take a look at mine, I can figure out exactly how the mechanism is to function before making such a bushing with close tolérances with rod fitment.

There were two options we could have used to accommodate the curve in the rod with such a thick bushing. One would have been to put a curve in the bushing but then you would have had a "front" and "back" to the bushing and someone would be sure to install it backwards. The other was to adjust the tolerance in the bushing inner diameter to allow it to travel the curve but still provide support. The second was the easiest option and as it turned out it worked great.

Ok, now I got the picture... just thought there was extra martial to keep the rod more centered and secure.

That part i over looked in the thread, probably because of the pictures, so I guess I was only seeing 1/2 of the bushing fix.

Thanks for clarifying and posting the pix that did not show up on the 1st page.

Yes, I agree now, you will need to do a bit of specialised machining. Even if i tried to make your style by hand, the fit would probably be worse than my original bushing as for how your new style is made.

Delrin would work well also, as I was pleased on how well it cut without melting doing dry cuts.

One note from my experience - use silicone grease instead of petroleum based grease on them. The Delrin doesn't seem to like petroleum based grease.

That I did not réalisé, though my usage with Delrin and Teflon has been without any lubricant usage. Both types really don't require lubrication, unless you have rust from condensation. Though, the rod is stationary, one can keep the areas in question clean and covered by mounting a plastic collar to collect drips and such when applying lubricant for window up and down function.

I Should read up on Delrin limitations, as I thought it was a harder Teflon material, that was immune to lubricant breakdown of it's compound.

Thanks for bringing it up!

Due to the arc of the rod as Pitcrew talked about earlier in the thread, they wanted to bind or stick slightly so I had put a little white lithium grease on it which worked fine. About a year later they started chattering and acting bad so I pulled one apart to find the rod was all sticky. I cleaned everything all up on both sides and put a little Super Lube silicone grease on them and haven't had any problems since. I didn't look to see if Delrin reacts to petroleum products or not but this is what my experience was and though I would pass it along.

This is from Super Lube's website -

Silicone Lubricating Grease with Syncolon® (PTFE) has a wider operating range than petroleum based lubricants; Excellent water protection and moisture barrier. Use on Plastic gears, plastic threads, as a damping medium for Dash Pots, lubricate O-Rings, electrical motor bearings and rubber components.

Silicone Lubricating Grease withstands temperatures from -40°F to 500°F.
