The front end seems a little hoppy- has anyone had tired front leaves and experienced this? Also, is it safe to put on helper springs as a temporary fix?
Well, my time went so quickly,
I went lickety-splitly
Out to my ol' 55.
As I pulled away slowly,
Feelin' so holy,

My truck sets about an inch lower on the drivers side front as compared to the pass side. I don't know about it being "hoppy" because I've never driven another truck like this. It does have pretty bad bumpsteer when you hit a bump at hwy speeds. | | | | | Joined: Mar 2011 Posts: 667 Shop Shark | | Shop Shark Joined: Mar 2011 Posts: 667 | Been looking all over to cure a similar issue on my bus but it seems that all the shops that used to "re-arch" springs have gone the way of the horse & buggy in these parts. Anyone (anywhere) know of a shop that still does this type of work? | | | | | Joined: Jun 2011 Posts: 420 Shop Shark | | Shop Shark Joined: Jun 2011 Posts: 420 | i live in suburb of philadelphia pa. we havea place here that I worked at years ago and is still in business, I just used them to re-arch and rebuild my front leaf springs so I could use them on my new 3" drop axle, name of the co. is delaware valley truck spring, on unruh ave. in phila. | | | | | Joined: Aug 2007 Posts: 37 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2007 Posts: 37 | I had the springs re-arched on my 76 3/4 ton 15 years ago and they are holding up fine. It gets most of its use as a hauler. Boise springs works did it. They are still in business. I am sure there are many other good spring shops still going around the country.

"Hoppy" might be related to the shocks.
I replaced the front leaf springs, rebuilt the shackles and installed new shocks on the '54 3100 last winter and Oh what a difference it made.
My words of wisdom; be sure to end up with made in the USA parts and do not fall for the cheap Spring Eye bolts.
