Door Scrunch Fix

Postby Paul » Thu Dec 13, 2007 1:12 am

Hi All--

CabezonBD has asked me how I modified my doors to eliminate opening and closing difficulty caused by the door position control widget. So thought I would post this project.

My doors were making scrunching noises and were very rough to swing thru their range of motion. The problem was the roller on the door positioning control. It would mostly not rotate when the door was moved and the cam would then skate over the frozen roller. I tried all sorts of lubes and had only a little temporary success.

So, I decided to replace the OEM rollers with ball bearings and this has worked very well.

To do this one must remove the hinge from both the door and the body. Not too hard. Use a pencil to outline the hinge location on the door and body before you remove it so as to be able to get it back in the right place. Block the door up and restrain it from falling sideways and remove the bolts from the top hinge. These bolts are tough to get at but can be removed with a couple of different angled box wrenches. Remove the hinge to your vise and drive out the OEM roller pin along with the roller. Now tap the hole to 8 x 1.25 mm. The hole size will be a little large but is OK for this tap.

Make up a special stud from an 8 x 1.25 x 45 mm bolt. This will be some harder as a lathe is the preferred tool. Here are some photos:

The smaller end is machined to 1/4 inch diameter and threaded most of the way to the shoulder to accommodate the bearing. I used 1/4-28 with a nyloc nut.

You will need to buy some of these bearings, R4ZZ. They are .625 OD x .25 ID x .194 thick. I found mine on ebay and just found them listed there again.

Now thread the stud into the hinge where the roller pin used to be. Might want to use some Loctite here. Slip the ball bearing on the stud and retain it with the nyloc nut. Bolt the hinge back in place.

Here is a photo of my door with the new ball bearing roller:

This works well and for me was worth the effort. Hope you like it.

Andy--

Well, I guess I could but I'm pretty sure you all would get them faster by making them up yourself. I still have my second (work truck) to do which is 'scrunching' on the passenger side. It is hard to get to all these good projects.

Paul, thanks for posting this, it's a great fix. Here's a variation that doesn't need machine tools. Use a 1/4-20 x 2" cap screw, flat washer and split lock washer.

To assemble, put the hinge in DOOR CLOSED position, put the spring in place first, squeeze the spring with channel locks, insert the bolt, flat washer, split washer, bearing and nut.

Here it is back in place.

Oh, wow! That's pretty cool! I didn't even know mine were completely missing until I read this thread! The spring bar just rubs on the body - and yes, it makes and awful racket every few months when it dries out.

Yet another project to add to the list, lol!

Does the original pin come out fairly easy?

Not bad. Put an old 3/4" socket on a workbench with business end up, position the hinge on top with the roller inside the socket. The socket acts as an anvil to hold back the hinge. Drive out the pin with a punch and hammer. If you don't have a punch, use a 1/4" bolt and toss it when you're done.

Sounds easy enough. I had the tires and wheels put on my truck last week. They needed balancing. Trucks looks much better. Thanks!
