This video focuses on the last and most crucial part of installing your anti-roll/sway bar, setting the preload. Even though some say you won't feel the affects of having incorrect preload, ensuring you have achieved zero preload is very important for high performance driving.

This has to be one of the best car how to videos I have seen. Straight to the point, short and simple.
i was thinking the exact opposite. "...By just putting a bolt in the sway bar..."
That didnt explain anything
thank you. for some weird reason there isn’t much info online about eliminating sway bar preload. this video was perfect
Just bought a front and rear swaybar kit. Didnt know zero preload was a thing but makes perfect sense. Thanks 👍
This is the only video on this subject that RUclips needs
Very well put together video.. clear camera footage, and communication to the point. Wish there were more DIY videos like this.
Aaron Bains thanks for the input, the more subscribers and views I get the videos like this I can do. Do you have any DIY's you'd like to see?
Perhaps a video about tuning the suspension and coilover preload, etc.
Aaron Bains awesome I will look into it
@@BenFreedmanRacing so?
@@dafunk420 I looked into it, sorry I didn’t personally inform you.
after a long search through youtube I finally found the perfect video. I’ve read through forums but im more of a visual learner. Reading tons and tons of instructions just confuses me more than it helps 😂
Us owners of Rover 75 MG ZT have a right game with this, as we use the coilovers off the E46 and a E39 drop link. But when it comes to adjustable drop links that tricky to setup. So thank for the how I’ll try it.
Great video. I’ve got an E36 too, so that was a nice surprise.
that's the nicest i've seen it done, good job
BELLEFREAK thanks! Feel free to share with others!
Agreed, This channel deserves more subscribers. Sub'd
very concise! Thanks
If you made more e36 diy videos this would be my favorite channel.
Aron Dillon thanks! I wish I had time to make videos more regularly but I will keep creating new content, just not as fast as I would like
Thanks! This was a quick good video!
so simple! Thanks!
this is exactly what i was looking for
great simple video, great job
Excellent video, straight forward, simple and easy. However, I wished you have done two wheels/sides rather than one wheel, to see how to balance both endlinks for either front or rear wheels.
Great and informational video.
Simple . . . Excellent . Stay Frosty
Very good method, unless you have no space with level floor...
Thank you :)
Awesome!
Most diy sway bar videos are wrong, didn’t show when put sway bar back, the end link needs to be 0 Pre-load and both left and right needs to be the same height
if you do this preloaded youll get noises for sure. found out the hardway
Did the same thing need to be done to both side
Subscribing is a great way to show me this video helped you!
Thanks for the guide. Why did you tighten/loosen the wheel lugs at :40?
I think it was part of his intro just coming through at that time.
Dawg I’m an idiot. I gotta have like so much preload in my sway bar lol. I’ve been doing this incredibly wrong.
Time to put it on blocks lol
Does the sway bar need to be set at a specific angle before finding zero preload?
This is what critical question i’ve been looking for but with no one answer for it 😂
From my understanding and research, the bar ends should be parallel to the ground. In any case, with one link disconnected and the suspension pre-loaded (settled), this will net 0 pre-load. Most difficult part, the driver needs to be in the car at the time, and someone else adjusting.
@@dcpatters0 or maybe put some weight in the drivers seat approx the same as the driver.
Here's a question. How do you know that the link which is left connected isn't preloaded before adjusting the one on the other side?
I did this but unfortunately my roll bar was rubbing on my driveshaft on one side, does this indicate a bent/ worn roll bar
Nice video! After doing this on one side, do you then undo the opposite side and repeat the procedure ?
Refine Movement you would do it just like in the video. Keep one side attached and perform what you see in the video and your preload will be set correctly. If you repeated this on the other side you're just doing the same procedure twice. Which isn't wrong but it is just more work.
benvidproductions awesome thanks !
Refine Movement thanks for your interest
angelo calimlim yup loosen one bolt, if you find the bolt does not slide in and out easily with your car on a level surface, the bar is preloaded. The sway bar isn't useless, if there is just a small amount of preload and you don't do any competition I wouldn't worry about it, just enjoy the car. If you are running the car competitively it will effect the balance of the car enough to effect your times depending on how bad its preloaded. Good question!
Ben Freedman Racing when you set the first side of it does the angle of the bar need to be horizontal to the ground or is it based on car? Mine is an e9x M3 and needing to redo the fronts
Great video, just one question... Do you not need the front two tires at the same level, on wooden boards as well, to balance the weight of the car all the way around? Or can you achieve zero preload just doing the rear first (on wood or ramps) and then doing the front second (on wood or ramps)?I'll be installing adjustable front and rear sway bars and end links soon and want to achieve zero preload. I have ramps and two jacks at my disposal here at home. Thanks so much for any input you can provide.
That’s a good question. I know in my case I was able to do it because my garage floor was very level and my ramps were short and the exact size. If your ramps are taller I’m sure it would work as long as your car is corner balanced and aligned. I’m sure there is a threshold where ramps could be too high and it could affect things but I’m not exactly sure what that height is but I think you could get pretty close with ramps even at 10” high.
After doing that on the blocks, could you jack it back up and put it on Jack stands to torque everything to spec or must you torque it to spec when lowered on the wheels?
Torque it with suspension loaded (on the ground or on the blocks) you don’t want the wheels to be free floating
@@Wooden_Hammer yeah I ended up buying some rhino ramps and lowering the car onto those to torque everything. All turned out good.
@@Wooden_Hammer can't speak on every Make and Model or brand of suspension equipment, but I'm currently messing around with BMR stuff on my 5th gen Camaro, and the guy from BMR told me the car does not need to be at ride height to torque the end link bolts/nuts down. He said everything with a bushing needs to be torqued at ride height.
Is it safe to put all four wheels on wood planks so the entire car is level when adjusting all the sway links?
safe and the best way
Im a noob to this could tell me why you want or need zero preload please

Bimma velvet blue: Because when you are driving straight, with the normal weight of the car on the suspension, you do not want any torque on your sway bars. That way, your sway bars will only be doing their job in cornering. This also means that the best drop-link (aka end-link) adjustment should be at zero preload with the weight distribution the same as when actually driving. That is why you should adjust for zero preload while you have the weight of the driver in the driver’s seat. If you are doing high-performance driving or racing, this becomes more important.
How do get the angle of the bar were you eant it
You should be able to use the adjustable links to get it where you want it. If the links are limiting the angle you are trying to get you can always buy longer or shorter adjustable links of the same style to get it where you need
Do you do this process for both sides?
Only the one side just like in the video. You will have to do it for front and rear
@@BenFreedmanRacing I have some adjustable sway links on a Honda so the zero preload you would want the ends of the sway bar parallel to the ground like an equal sign basically?
How to tell if my endlink are loose and need adjustment? My car making clunking and squeaky noise over bumps in low speed at the moment not sure if its bad coilovers or the endlink need adjustment i have adjustable endlink by the way
Super mariyo that sounds more like bushings or balljoints possibly. I would just visually inspect the endlink to rule that out. But make sure it isn't a more crucial part of your suspension that is making that noise to rule out anything unsafe
Take a look at your endlinks. After I put BC coilovers on my e36 m3 and the suspension settled I noticed that the swaybar endlinks were too long both on the front and rear. The endlinks links were resting on the lower control arm. If you lower your car, E36 in specific, get shorter endlinks or adjustable ones.
Nice man, very nice!
