I wanted to do sway bar upgrade because of body roll

When I go around fast curve, My XF couldn't make well because of rolling.. eapacially comparing with my saab 9-5 aero

I tried to find an aftermarket performance XF swaybars to around world.
but nowhere exist.

So, I asked to korea swaybar manufacturer to make custom XF swaybar
and finally have only my item..

I'm very happy to drive my XF, and don't have to hesitate to turn corner

 

Wow, that's impressive! Will they make more for you? I bet you could sell some pieces...

I think that the XF swaybars will also fit other models, I made some investigations a while back. https://www.jaguarforums.com/forum/w...-f-type-94044/

What are the dimensions/thickness of the new ones compared to the old ones?

 

as I attach photo above, all XF turbo & supercharged use same sway bar

stock one thickness : front : 31mm ... rear 16mm
new one thickness : front : 32mm ... rear 20mm

# stock one front is like a pipe .. new one front is like a mass
therefore, the difference is just 1mm but strenth is very different..

 

Solid 32mm! Wow...

Yes the front bars on other models are hollow too.

Thanks for the information, can your supplier make more of these?

 

I will suggest to the supplier to make more & sell through e-bay..

As my experience, Price will be around $400~450 with bushes

 

That's a very reasonable price I think, not much more than the OEM Jag ones.

 

Cby210, are saying that these will fit all 2009 XF'S or other years too?. It does not appear you upgraded your springs. Do you feel the sway bar upgrade is all you need to improve body roll. My 2011 XF SC even in sport and dynamic mode still rolls more than I would like. With only 20k miles it seems to have more roll than a year ago. I was thinking new springs would help, but sway bars may be better answer?

 

I think, spring & sway bar(= anti-roll bar / stabilizer bar) have different role.

Spring is related to bounce (up & down) but sway bar is not

So, If you want to reduce body roll, you should upgrade sway bar.


I'm very satisfied with current setting (stock spring & shock absorber)

As I said above, after upgrading sway bar I'm not concern about body roll

# I can drive faster at the curve without concerning. also Feel heavier handle


[P.S] 2008 ~ 2015 .. all XF diesel turbo & XF supercharged engine car use same sway bar ( same parts # )

.

 

Improved swaybars with stock springs/shocks are definitely better than just lowered/stiffer suspension.

Which is why I have wondered why nobody made an effort in the aftermarket with such a product.

I think it might be because shocks/springs are relatively easy to install on these cars, but swaybars take a lot of effort, because you have to lower the subframes (the swaybar is located between the subframe and the body of the car) well at least that's how it is on the XJ and S-Type, I assume the same on the XF...

 

You are right .. not easy work .. but much more satisfaction ^^

 

Wow that does look like a lot of work haha. Good call on that upgrade though. Did you do the install yourself or let a shop have at it?

 

Fantastic! I always missed particularly a decent sized rear sway bar on ALL Jaguars. They certainly placed the bars in such a way that it takes a lot of work to change them, as opposed to many other cars (or earlier Jags, such as my '05XK) where a bar change takes a matter of minutes.

I'd also be very interested also in a description for what work it required to make the change? How many hours of labor?

 

Very nice. Keep us posted. I am sure many people would appreciate this upgrade.

 

I asked to a car repair shop^^

 

I'm sorry but It's hard to explain a whole working process because of my poor english & not familiar parts or work name

You should ask to a shop that can take care of changing sway bars.

I assume that It takes 2~3 hours to remove swaybar & install new one

 

Thanks. Jagswagger

 

If the shop has all the required equipment, and is familiar with these cars, then maybe 3 hours per bar, but I would expect it to be a bit longer than that.

From your pictures the chassis/subframe arrangement is very similar to the S-Type & X350 XJ. You could find the work instructions in the JTIS Workshop Manual, it can be downloaded here on the site (does not have the XF in it, but the procedures would be very much the same).

Front:

Raise car
Remove wheels
Remove brake calipers & support them off the body (cable ties)
Unbolt the shock at the lower bush
Unbolt the vertical link and support it
Unbolt the swaybar links, the front lower wishbones are now hanging
Unbolt the steering rack from the subframe
Support the engine from the top with an Engine Support Bar
Unbolt engine mounts
Unbolt front subframe and lower it about 1 foot with a large jack
Unbolt sway bar, remove & replace with new one
Reverse all that to put it back together

Rear:
Raise car
Remove wheels
Remove rear exhaust section, then center exhaust section
Remove brake calipers & support them off the body (cable ties)'
Unbolt shocks at lower mount
Unbolt sway bar links
Unbolt upper wishbones at the top ball joint, rear wishbones will hang down.
Unbolt the propshaft fromt the diff, and support it
Unbolt rear subframe and lower it about 1 foot with a large jack
(I think you might also have to unbolt the electric handbrake motor, or at least disconnect the wiring)
Remove swaybar, replace with new one
Reverse all that to put it back together

When I had the rear swaybar on my XJR replaced with an XKR-S one, the guy was able to get it in/out by only lowering the rear of the subframe, with the bolts still in the front, just loose to allow movement. It was still a lot of messing around.

Yes a lot of work involved, but worth it I think.

 

Wow. .
You must be an expert..
Thanks Cambo.

 

LOL, no, I just looked in the workshop manual

You have polyurethane bushes on your sway bars, have they been squeaking? I put poly ones on my rear bar and they squeak when I drive over speed humps, it's very annoying...

 

Yes. I put polyurethane bushes that made by swaybar supplier.

He said that every a year or 2 years, I should add urethane bush grease.

The grease is very sticky.

Until now, no squeaking noise.
