My passenger side suspension seems to be sagging, I think the guy I bought it from had a larger passenger because it seems the seat is bent and the door panel has been replaced. Is it possible that this heavier load has worn out the spring? Also when I drive, it seems to want to dart from side to side, not excessively but just enough to be a little annoying, the tie rods seem too be tight and all the bushings have been replaced with polyurethane ones. It use to have a steering stabilizer shock that I removed and I wonder if this has worn out the steering box? What is the tolerance of movement for the steering box?
Thanks

Front springs are easy to replace, plus they are not expensive.......unless you are lifted
I used these.......lifted the front back up about 1.5 to 2" plus the newer springs are progressive rate.....they were $102.00

I'm not lifted but I do have the dual front shock option and I looked at the link you gave me, I think that is for single shock only?

If I change the springs do you think that will help with the serpentining?

 

I have dual front shocks also......the springs work and fit perfectly fine....I don't know why they say they don't......when I did mine I removed the old one and took it with me to compare......I thought the diameter would be different but they are not.....I've had them on for a while now......so maybe it's the spring rate that's different for single shocks......I'm guessing it would be stiffer for single shocks......which I was good with...since they were progressive anyway they ride great..........and are good offroad
I would put the steering stabilizer back on......Rough Country has a good HD one

 

Gotcha, that makes sense to me about the springs. The stabilizer when it was on made the steering basically stick one way or the other so there must be some play in the steering box, I replaced one once on my one ton 4x4 and was not real impressed, got it from napa. I'm afraid of sinking money into another crappy rebuild, any ideas?

 

Did you do the balljoints? I heard a theory from someone that sounded good.. the balljoints will get stiff from age, when you steer the balljoint sticks causing you to oversteer a bit to correct for it..

How is your alignment? gaining an even amount of positive caster made a huge difference in straight tracking for me (at like 4.5degrees), more than I expected.. and camber is really tough to get right on TTBs but will also make a huge difference in how the frontend feels. People also never blame tires for steering problems but they can cause plenty of steering issues.

Are your wheel bearings okay? They make a huge difference in how the frontend feels, make sure preload is right and one didn't come loose or is starting to go bad.

and about the passenger spring, it was probably not due to a fat person. The front passenger side takes a lot of abuse in any vehicles, potholes, curbs, etc. It's usually the first tire that blows, the first shock that goes, the first spring to sag. I'd bet when you change those springs you'll notice a huge difference in how the Bronco drives, I'd do the springs and then follow up from there.
At the very least, the one sagging spring is causing your alignment to be off and if you can see the difference in level, you probably have a pretty big camber difference from driver to passenger side.

 

Oh, I dunno how many times I've seen on the internet in different forums people with F-series or Broncos swapping those Moogs in and they seem to go on and on about how much they love them. Even people with springs in good health swap them in and act as if they got a whole new vehicle.

 

Ok,
I'll do the springs and go from there, thanks so much guys for all your input!

 

It's the progressive rate on new technology springs......can't beat it
