Truck sways severely at highway speeds

Hey guys, quick question on what I can do to reduce the swaying on my truck.

It occurs when I've got boats on the roof racks, so throw at least 100 lbs on top of a Leer Cap to get the picture. It usually happens when I go over a bump or pothole on the highway, most of the times the swaying is mild enough that it doesn't worry me but every now and then it oscillates at a rather alarming pitch and I have to slow down to get it back under control

So what to do? My rear leafs are sagging pretty fierce, they're frowning and due for a replacement. Would that alone fix it or is there something else I should be looking at

Thanks

 

New suspension will help for sure if yours is worn out. Your shocks could also be shot. It is worth checking the condition of your sway bar too.

 

New shocks alone would probably help a lot, so if you are working on a budget, start there first.

 

Except that if you replace the shocks with stock length shocks and then replace the suspension with lift springs later on, your new shocks are useless and will need to be replaced again.

 

That and if your leaf packs are crap the new shocks will just get over-worked.

 

Unfortunately you should look at a combination of what everyone is saying. Replace the leaf springs and get a better pair of shocks. Weak leaf springs will cause poor suspension control, and with a higher center of gravity with things loaded on the roof, you are multiplying the problem.

 

New leafs/shocks would help for sure. Do you still have your sway bar on? Is your truck stock or lifted?

 

Old suspension + old alignment = mucho movement

In these trucks I'd say shocks alone aren't enough. You might as well replace the coils and leafs as well, because they're worn out too.

Oh and get an alignment. My truck felt a little less sketchy after a good alignment.

 

So if I were to prioritize what I should replace (as money is a lil tight and I can't do it all at once)

1) Leafs
2) Coils
3) Alignment

thoughts?

 

Free alignment check first (just a check out... see if anyone will do it for free).

Then start with new suspension parts. If you aren't looking to lift the truck at all, see if you can find a shop that would be willing to work with you to rework your leaf pack. Then get some new shocks/coils and you should be set.

 

Cheapest mods first:
Take the crap off your roof.
Drive slower.
If that doesn't help, park it, get your money together, fix it, and make the vehicle road worthy.
JMHO
