I recently bought a 1999 Ford E150. The sliding door is sagging on the front end. We tried adjusting the bottom roller assembly on the inside of the door but this didn't actually help.
We noticed that the there is just bare metal that the bottom rollers ride on. Is there supposed to be an insert that the horizontal bottom roller is supposed to ride on? The whole door is very loose and prone to jump off its top track.
It's tough to find any info related to sliders on the web. I think the best way to go is to remove the door and see what's what, more than likely you'll need to replace some rollers at the very least. There's three sets of assemblies, top, middle and bottom that the door hangs on.
Does anyone have a photo of their top and bottom door tracks they can post for reference?
It almost looks like the vertical wheel at the bottom slider part bolted to the door should be riding on something, but it is riding on just bare metal. Jacking the door up and adjusting the bottom roller arm down doesn't resolve the sag issue at all.
The top, middle and bottom rollers all ride in a track, you should be able to see any wheel at the bottom without looking up into the track. I'll try to get some pictures tomorrow.
Mine are in tracks. I'm curious to know if the bottom (horizontal surface) of the lower track is supposed to be bare metal or if there's supposed to be an insert of some sort. We just can't seem to get the door up high enough.
There's so much drop that the top roller once fell out of the top track when we had the door open all the way.
So it does just ride on the bare metal. Hmm. I wonder if that part on mine is really worn, or if those rollers are adjustable? I think we're going to have to jack the door back up and get that part out for inspection.
I'd be interested in how your repair works out, if you don't mind posting after completion. I'm wondering mostly about those rollers specifically to see if they're something that could be sourced through McMaster Carr of other industrial supply. That would negate the need of buying the complete assemblies and save a lot of money.
The old parts looked fine, but I can tell you it took a lot of effort to slide the door back and forth and at one point the top roller fell out of its track.
After installing the new top and bottom door rollers the door was the right height again and the door slides easily.
The door itself is damaged though and bowed in from about centerline to the top, but now it actually closes all the way without sagging.
From start to finish I think it took us less than ten minutes to swap out the top and bottom rollers.
