Gary Lewis Posted April 6, 2022 Share Posted April 6, 2022 Label says same thing. 9100 lb GVWR and 4500 lb GAWR front. I guess I’ll keep digging. I'll check the 1980 dealer facts book today to see what it says. I don't have it online. Link to comment Share on other sites More sharing options...
Gary Lewis Posted April 6, 2022 Share Posted April 6, 2022 Label says same thing. 9100 lb GVWR and 4500 lb GAWR front. I guess I’ll keep digging. I'm not seeing a table in the 1980 dealer facts book that shows the various GVWR's. But I can see your axle ratings. There's a Payload Package Selector table, and in the Opt column there's a 2041 (4500) selection for the F350's front axle and a 2834 (6250) rear axle option. Plus a note that says "Front and Rear GAWRs will in all cases sum to a number equal to or greater than the GVWR for the particular vehicle." And on the page for Options the Snow Plow Preparation Package says that a 2041 kg (4500 lb) front axle is included. Link to comment Share on other sites More sharing options...

Do you remember by chance where the 3485# rating came from in the cross reference you posted above for the E0TZ-5310-U spring? Link to comment Share on other sites More sharing options...

Documentation/Suspension & Steering/Front Suspension then the Part #'s tab, Springs tab, Cross Reference Chart tab.

Atlas75 Posted April 7, 2022 Author Share Posted April 7, 2022 Yes. Documentation/Suspension & Steering/Front Suspension then the Part #'s tab, Springs tab, Cross Reference Chart tab. (Man, that stuff is hidden! ) No worries! I got there. Two questions: 1. How can E3TZ-5310-R be listed as both a 3290# and a 3485# spring? 2. What does the star mean? The r/b means "replaced by" according to the abbreviations section of the Ford master parts catalog. So depending on what the star means, do I interpret that to read that E3TZ-5310-R replaced E0TZ-5310-U and E0TZ-5310-T (which would negate my 1st question above)?

The star means it is NLA, as explained below. And it looks to me that they actually did away with the 3290 E0-T spring and replaced it with the 3485# E3-R spring. I'm guessing that there just wasn't enough demand for the 3290# spring to warrant having it. Link to comment Share on other sites More sharing options...

And now I know which spring I need! And it is readily available! Thanks for your help nailing this down Gary! Link to comment Share on other sites More sharing options...

Atlas75 Posted April 10, 2022 Author Share Posted April 10, 2022 Happy to help. I had a chance to pull the passenger front shackle today. Now that it is out of the truck it does not appear to be bent. The bushing however was in rough shape. I think the poor condition of the bushing made it appear to be bent. I was able to remove the bushing and now I just need to find a replacement. The center sleeve was almost resting on the shackle without any weight on it. I’m sure it was touching when the weight of the truck was on it. There was also a rub mark on the shackle where it was touching the frame. I’m fairly convinced that rebuilding the front end will resolve a number of issues. Now I just need to find a good place to get springs. Link to comment Share on other sites More sharing options...

Now I just need to find a good place to get springs. There are two types of bushings: rubber, like Ford used, and poly, which most aftermarket companies sell. The rubber ones are softer and isolate better. But I've used poly for my rebuilds. I've not bought springs, but I bought some spring liner material from Eaton Springs and they really seemed to know their business. Link to comment Share on other sites More sharing options...
