Steering and suspension

[pelky350]

after paying much attention to my motor and fixing various things I think it's time to work on my suspension and steering, but where to start? Rear drive line had new or good u joints fresh carrier bearing but upon take off it feels wobbly or bouncy axle wrap feeling just feels loose and almost feels like something is shifting if I add more throttle almost like broken motor mount? Transmission mount is new. Clutch is new, carrier bearing new, shocks not old. Axle has been changed out once with lower mile axle couple years ago

Axle rap is real bad in these trucks especially with a lift, I had a terrible case and replacing the worn out shocks with some pricey bilsteins seemed to really help as well as make the truck ride much better. I would start there and then maybe start replacing your rubber suspension bushings with poly bushings

Rancho rs5000 are on now and only couple years old, they did help but something just feels wrong, still stock height 4 inch blocks from
Factory, just normal driving it feels loose and something is squeaky somewhere almost sounds like leaf springs are loose I checked the u bolts but they are as tight as a 1/2 breaker bar will tighten them

Checked you're pinion yoke? Mine's loosened up a couple times now. Normally is more of a vibration than anything.

I have the same feeling in the back of my F350. I've thought about building some axle wrap bars to help hold it in place. But haven't yet. I just did Bilstein shocks and it seems better than before. With you having newer rancho's though can't believe newer shocks would help. I personally think it's the 4" blocks that do this. My F250 I don't notice any axle wrap in.

You can build traction bars or buy a set meant for the obs trucks, they work just fine on the bricknose. How do your rear anti roll bar bushings look?

If by anti roll bar you mean sway bar my truck didn't come with one, there Is a ting noise like bad u joing occaisionally but under truck inspection shows nothing, everything just feels like jello when i take off. Is it just because of me adding power mods to my truck maybe, More torque causing me to thing stuff is loose? I noticed this more after my recent turbo swap from 088 to factory with Russ' mod I think

What are you guys doing that you notice axle wrap in these trucks? I have used my truck hard for 200k and never once thought I needed to control axle wrap?

If you have a auto it's probably not as noticeable

 

[Thewespaul]

I notice it the most when taking off from a light in the rain. The slip a bit and then you get into that terrible jolting axle rap

was auto, now manual, never notice it, but I don't spin the tires....

I try not to also only happens and when is wet outside or I'm on gavel. But my truck just feels like it's got wheel hop/axle wrap just driving around like normal person. There is a slight wobble in rear right wheel also but it's not tire/rim related it's been there through a couple sets of tires and rims now, though it's only very slight and only when empty bed

As to your question of where to start I recommend the RSK from Precision Metal Fab with 99-04 Super Duty springs. It has been hands down the best upgrade I've done for comfort. And someone else already mentioned poly bushings, I second that. Energy Suspension makes a great set. Lastly steering wise check out Carrick Customs for their tie rod and drag link setup.

Also your hop might be from drive line vibrations. The crew cab long bed's sometimes need their carrier bearing shimmed down to keep an odd vibration that sometimes feels like wheel hop due to it being very slow. I have it happen somewhere around 38MPH so I just don't hang at that speed much.
