Springs

There has been lots of discussion about axles, but not much about springs.

I'm going to replace the springs on my 58 (I think) and aside from finding out the width is different on new springs, is there anything else I need to know about springs as I look for replacements?

My thinking is that after 46 years, its good insurance to replace. I've also had the thought that since its duel axle, no biggy if one breaks, however, there is a certain law that says when it does break - it will be when I don't have time to get if fixed, thus I want to replace and not have to worry.

Thanks - yes I admit it, I do like to really understand this stuff and I do read a lot. After reading the one article - it convinces me more to replace the springs.

Any other spring ideas/thoughts out there?

Ken

Ken,
I just began the task of a complete brake and bearing job on my 60 Overlander.I have dual springs (dual axle). Once I removed the backing plates I noticed that my bushings are shot! So I made the decision to go ahead and remove the springs and either have them rebuilt or purchase new ones and replace the bushings at the same time. If I find out any helpful information I will happy to pass it along to you. I did read a thread where someone had their springs resprung, I don't recall where that thread is.

Good Luck

Steve

Thanks - as a matter of fact today I'm moving the 58 about 50 miles to the welding shop. My bushings are in bad shape also. I'm gonna just go ahead and buy new springs because I want to make sure all running gear is new. The welding shop (that does axle work) is going to do all the measuring for me and I'm planning on buying from dexter. Have a choice between 1500 lb springs and 1200 - 1500 would give 6000lbs and 1200 would give 4800 - do you have any thoughts on this? Also buying new axles and coupler. We will keep in touch.....

Ken

Thumbs up

Ken,

I found a trailer shop Orange Products Inc. 2 minutes from my office. I showed them my old backing plates, drums, bearings etc... and they were able to match everything up right on the spot, they even back my bearings and pressed in my new main seal. They to are using Dexter. As far as the springs go, I have not got that far yet! If you go with the higher rated spring it may ride stiff unloaded but once you have all your gear loaded up it should ride nice.

Good Luck

Steve

Thats great - if you need the number for Dexter, let me know - they are very Vintage Airstream friendly.

A friend told me about Del Run (sp) bushings - anybody know about them? Supposed to be far superior than rubber.
