DIY Rogue Monoball F8X

Tools needed for this job are:
8mm socket for wheel liner
T30 socket for removal of 1 bolt holding cooler
Zip ties to keep cooler out of the way while removing long bolt
18mm socket and extension to get bolt from frame side of thrust arm
21mm and T40 sockets for removal of nut at bottom of knuckle(21mm wrench for installation of the nut)
Hydraulic press or my preference of a bushing tool from FCP Euro
Grease for installation of monoball

Remove wheel
Remove wheel liner
Remove T30 bolt from cooler
Lift cooler up out of two rubber grommets at bottom of cooler
Zip tie cooler to something high in the wheel well, being mindful of not kinking any of the rubber hoses
Remove 18mm bolt from frame
Remove the 21mm nut at the bottom of the knuckle. It will likely come off without the use of the T40, but likely will be needed along with your wrench to install.
Remove thrust arm from vehicle
Press out oe bushing
Pre grease side of monoball and inside top edge of thrust arm
Press on Monoball with large side facing out
Install body side 18mm bolt first and tighten to 81 ft/lbs
Install arm into knuckle
Put closed end of wrench on nut, then T40 on your ratchet and turn the ratchet counter clockwise, which will thread nut onto thrust arm, tighten to 60 ft/lbs
Re-install wheel liner
Re-install wheel

I like the bearing tool. Way better than taking it to the shop mid project.

I could not agree more. According to FCP Euro this press was not for the F8X, so I considered going to my local shop, but when they quoted me $175 for pressing off the old bush, and installing the monoball if I drop off my thrust arms I decided to take my chances with buying the Press tool. Sure glad I did!

What is your feedback with respect to NVH after the install?
I have the fall line units and it was, far and away, the noisiest upgrade I’ve made to my car. It seems to be noisier inside the cabin than out. I’ve even considered taking them out because of it.

TBH, with the Rogue, I have noticed zero increase in any nvh. I am on stock edc struts/shocks, and H&R sport springs. I am going to be installing KW CS 3 way in the coming weeks. Lets see if anything changes then.
Maybe talk to Ben at Rogue and have him hook you up to convince you to change over to the dark side. haha

Did you install a new M12 bolt ? The Fall Line instructions say you’ll get some extra noise if you don’t. It’s a tty and they probably stretch.

The only bolt I ever replace is oil drain plug, haha. I re used all hardware on this job, and am having no noise issues. If I develop any, I would consider springing for a new $12+ bolt.

I did a little bit of canyon carving, nothing too too crazy. Wheel feels a little more solid I would say, and also if I get a little happy with the accelerator in 2nd and 3rd when the rear wheels break loose car feels very controllable.
In my estimation doing the monoball is just a small part of tuning your suspension, but regardless of how small a contribution I will always do it to any car I know will be doing any track time at all.
Not the most scientific review, but just my anecdotal experience.

Dropped that puppy at the post office this morning. Looking like a Saturday delivery at the latest. Safe bet would be to get those arms off your car Friday night or Saturday morning and wait for your carrier to get that thing into your hands.

The tool worked to perfection. Easy out / easy in. Highly recommended for these particular bushes. It will be headed back your way USPS in the am.
thanks

I installed the Fall Lines as well. They are silent...No added NVH in my case.

Nice write up... fwiw I had the rogue monoballs on my e90 and then went with the fall line’s on my f80 as they were available sooner. Put almost 60k miles on the fall lines and from the beginning I noticed more nvh than I remembered on the e90 w/ the rogues, and it only increased over time. Only when hitting sharp bumps and turning while stationary, but in both cases they improved steering feel at all speeds while eliminating toe change and allowing the abs to work less while braking and hitting bumps at the limit of traction, def a great mod. Only other thing I can add is that while not absolutely critical, it’s best to torque the bolts for the ftab bushings at rideheight not full droop, I redid this with the fall lines and it eliminated the clicking while turning for a long time until it finally came back after 45k miles and 4 years, I’m assuming from stiction caused by dirt and debris as they don’t have rubber seals, but could be rebuilt with fresh inserts, the fall lines that is.

I didn’t do the install myself so I can’t say for sure. Perhaps I’ll have a shop take a look. Thanks for the feedback

For those that DIY’d this...

1). How long did it take you to remove and re-install the arms not counting monoball press out/in time?
2). Did you have to use a pickle fork for the ball joint at the knuckle or did it just pop off easily?

The whole thing not counting press time is like 2 or so hours. This is only so because of adding time for wheel/wheel liner, removal, and moving coolers out of the way.
No pickle fork for me, but at the time my car had maybe 23k miles, and I’m also in California where we get minimal rain and no snow. After removing nut from ball joint, and a little wiggle on the knuckle it literally is like fall of the bone ribs.
Honestly its a 2/10 difficulty.

Sounds like a weekday evening job then. I'll pop the tension arms off one evening, take it to work for pressing the next day, and then pop them back on. My 2016 has 13k miles on it so hopefully the ball joints just come out.

Crap! My ball joints are not coming out of the knuckle. Both sides stuck. I just don’t understand as this car has never seen salt. The nut came right off.

Any suggestions?

Sorry only saw this now.
You can start with some spray lube onto the ball joint, then let it sit.
Then you can hit the arm with a rubber mallet, but whatever you do, do not hit the ball joint itself. You can also thread the nut back on a few threads, and very gently tap the nut with the rubber mallet.
