Rear Sway bar?

[MattG]

Check for leaking oil from shocks first.... that's free

Will check for leaking shocks but I doubt that's the case. It's moreso me not being familiar with the Expedition in relation to my driving experience with F150s/F250s and previous SUVs.

I am going to get the Hellwig Swaybars regardless. We plan on keeping this Expy for awhile, even bought the Ford 7 year extended warranty. So, I don't mind dropping $800 on front/rear sway bar.

The sway bar borrows spring rate from the opposite side netting in stiffer spring rates overall. The bar eliminates a bunch of the up down stupid behaviors the Expedition has prior to the bar.

That's part of how they work, but physically a sway bar is more like a torsion bar. The sway motion in a vehicle produces a twisting motion in the bar, which since it's solid metal, it resists that twist and reduces the side to side motion of the vehicles mass above the center of gravity. This why it functions much like a torsion bar helping to as you said, move some of the weight between suspension components on both sides.

But it's all part of the system and all of it works together to improve ride stability and control. More detail of its function and a great description can be found here: https://practicalmotoring.com.au/ca...sway bar works by,wheels as level as possible.

Its 100% a torsion bar. It's using it's force on the opposite sides spring rate, essentially borrowing spring rate to stiffen the initial side up.

Just looked on the Hellwig site and nothing comes up for the 2020 rear sway bar. Any suggestions?

It’s the same as the 2018 model.

7688 for the rear and 7696 for the front if memory serves.

Are we stuck ordering from Hellwig at this point? I looked on their site and it says 8-10 weeks.

I've been waiting for my Hellwig bars for 8 weeks now...
Maybe week 11 is the charm!

Can someone post some install pics? Seems easy enough but I do not have a car jack and will be using ramps instead. It's best to install it while the vehicle's own weight is on level ground correct?

Ramps are fine, that's how I did mine. There are some pretty simple directions in the box, but just remove the end links with a small open end wrench, and a large wrench, holding the post in position while you loosen the nylon insert nuts. Remove both sides, then remove the bolts holding the bar to the frame. Install is just opposite but don't crank anything down until all end links are in place and secure.

 

[Deadman]

Ramps are best. SO there is weight on the axle.

I did mine on the ground with 35” tires. Ramps would be super nice and a lift even better. Just put on my MOOG links. Nothing to it.
BlueBeam has nothing on the iPhone
[emoji1787] not the best but here is a idea.

Great write up fozzy, as with anything, I would double check tightness maybe 50 to 100 miles, as things may settle in a bit.

Appreciate the pictures and write up! Question though: why the MOOG links? What improvements other than better quality versus stock does it give?

The factory ones are pretty much crud. Some have said they have broken factory ones, but as stated previously that could have been caused by numerous things other than just an upgraded bar. I personally didn't like the design, is was basically a press-fit connection with no real backplate to secure the end links. Most of the aftermarket ones have a better backplate or, like the ones I used, it's two bushings instead of metal on metal.

 

[Deadman]

Don't over tighten the bar clamps or the bar with squeak like crazy.....

 

[Blue87GT]

Was the factory end link greaseable like the moog version?

 

[5280tunage]

No, they aren't. all are static.

And to that point, try to clean up excess grease that my squirt out when you tighten them, excess grease will attract dirt quickly and likely cause noise as well.

I ordered from Summit on 1/1, and looks like the front will be arriving tomorrow. Rear is expected to be another month or so. Any thoughts on putting the front one in while I'm waiting on the rear to arrive? Or should I hold off and do both at the same time for a complete transformation?

 

[5280tunage]

The rear won't provide anywhere near as much effect, I would just get er done if you can. My luck the rear would be lost in shipping and I would be waiting even longer. The rear one I didn't even use ramps, there was enough room to crawl under and do it pretty fast.
