Lifted PSD's

I know that there have to be quite a few of you who've lifted their trucks. Not being familliar with exactly what years/models this affects, let me throw it out for your consideration.

Last year I spent most of my Sat. repairing my neighbor's '00 F-350 4x4 PSD. Truck is equipped w/a 4" lift and 35's.
He stopped by on Friday after calling from Les Schwaub, where he was having his tires rotated. He told me that they had spotted a small crack on the shock mount, and asked if I thought I could weld it up. I told him that it shouldn't be a problem, and to bring it by.

After crawling underneath to look, I summoned him so he could see the damage for himself. The lower track bar bracket is welded to the front axle housing, and incorporates the shock mount and spring/u-bolt perch. There is about 10-12 linear inches of weld connecting the bracket to the axle housing. About 1.5 inches remained intact. :eek: He had thought that the truck was wandering a bit. ;)

We repositioned, rewelded, and added additional bracing. I was concerned that we might discover a new stress point over time, but so far so good.

In subsequent conversations with others more knowledgeable about this problem, it seems that it's not uncommon. I have also been told that there is a lowering bracket for the upper mount that became available after this problem started to show up. I hear that it cures this angularity/overstress issue.

I truly don't know how common this is, or if it's common knowledge among the PSD crowd, but thought I'd mention it so that you guys could let me know what you think.

You mean Twin I-Beam, right Muddy? Or is that Twin Traction Beam?

That may narrow down the application for this problem. The situation I was dealing with was F-350 w/live axle.

How about the F-250's? are they live, or TIB/TTB? What years if so?

That's why I said I don't know enough about this. I'm willing to learn.

On the 94-97 F250's you have a TTB(Twin Traction Beam) or IFS suspention. You have two brackets that drop down to hold the axle to the truck.

One the 94-97 F350's you had a mono beam Dana 60 axle.

Me too, sorry, forgot about the TTB. Was thinkin' all live axle, even though I know better. Don't play w/them Fords much.
