Window Regulator

[Leon R]

Last night, I saw even more evidence that binding is caused by too much clearance. You can actually see it in my earlier photo:



First, the bracket angle appear to be smaller than 90*. I am not sure if it was suppose to be 90*, but it appears to be bent in a direction to cause too much clearance.

Second, if you follow the rail up, you can see it twisting, once again causing too much clearance.

Combine this with worn/cut glass run and you have a binding problem!

Allison, I wonder if your rails are still twisted, which could explain why new window run and regulator did not fix the problem.

Do we have any photos of this "metal rail" from when these trucks were newer?

In ether case, I will need to purchase a DS glass run, are they still available from Issuzu?

I see your logic but this is the age old "chicken & egg" thing.

Did your bent rails cause the regulator to go FUBAR or did the regulator fail letting the glass tilt which caused the rails to bend???

We'll probably never know. I'm attacking the one known problem: the guides for the vertical track can not hold up to the stresses put on them. After I get my arms wrapped around that problem, I'll look into the bent rail issue.

BTW, if your rail is bent & you just replace the glass run (rubber weather strip), aren't you just kicking the can down the road. The new glass run will cut/tear eventually.
