    Jake you are the only one that makes people understand what is all about 4 link
    You help me a lot to understand what and how to do it
    These 3 videos about 4 link are more than treasure to me and for most of us that want to build a reliable 4 link suspension

    Good stuff. I've been out of 4 wheeling for awhile due to life. Before life happened I was in the parts acquisition stage of building my Jeep. Since then I landed a sheet metal apprenticeship and to finish it out we do a project of our own for our 5th year. I decided I was going throw out all my brackets, tabs, skids, misc sheetmetal parts, build all of it myself, and finish my suspension. This, along with your anti-squat video, are really good refreshers. I just wanted to say thanks for sharing all this good information.

    Thanks for the great video... I'm starting a build using rockwells and noticed a lot of people use a single triangulated (lower) and parallel uppers due to the large chunk up top. The rear should not be a problem for double triangulated 4 link but the front is a challenge. Would you mind (if and when you time) doing a video like this one about doing single triangulated 4 link?

Would you be able to one discussing roll cages regarding design & fabrication and what are some "do's" and don'ts"? I'd like to build a new roll cage but not sure where to start from a design standpoint and where to take it from there.

I completed the front four link with limited geometry due to obstructions, however in the rear I have more room and was wondering how the upper and lower link horizontal spread at the narrow ends effect travel and articulation characteristics? Should they be as close as possible? Or are there aspects I should be considering when choosing the link bracket mount locations? Thank You!

  • @moparmtb360
    @moparmtb360 7 лет назад

    If you only run single u joints at each end of the front drive or rear drive shaft then the pinion angle should be the same angle as the transmission output and not pointing at the transmission. For example. My jk has a 4.0 swap and I intentionally mounted the engine and transmission level with the frame. So I can run lots of castor angle and single u joints each end. Great video.

    Hey Jake...Great information on 4-linking. I just have a quick question related to triangulation. In the rear of the vehicle, can the four links be setup with the upper arms straight (essentially running under the frame) and the lower arms be crossing with no track bar? Wouldn't this design setup (single triangulation in the absence of a track bar) lead to a rear steer issue and stability problem with the vehicle??? Would really appreciate your expertise on this question. Thanks - DMZ

      It won't have near the control of a traditional double triangulated four link.

    Not sure if the same rules apply here but im getting ready to start a mega mud truck build on my f350 superduty using 2.5 rockwell toploads. Alot of people tell me the upper and lower link bars need to be the same length and have the same link seperation at the axle as they do at the subframe. Along with a 15* link rise. And to keep the lower links parallel and only have the upper link triangulated.... any input would be greatly appreciated

    @vinniescarlata1278 6 лет назад

    GREAT video!! Thanks! How much of a difference do you think the shorter upper front links make for on road use. I see lots of 3 link + panhard kits using combination brackets (combines upper & lower mounts) for the frame and I'm wondering if this means I should avoid them and get individual brackets so I can do a shorter upper. I'm building an Jeep LJ on 40s and expect 75% road/25% off road use.

  • @skatefreak666666
    @skatefreak666666 8 лет назад

    one thing you dont mention when youre talking about rod end selection is you need to make sure that at least one of the link can rotate. since the link rotates some under articulation, you cant have poly bushings on both ends, as it will cause the link to twist and possibly break, or at the minimum, wear out the bushings very quick

  • @offroader22
    @offroader22 7 лет назад

    Do I Understand you correct?
    Identical length on the upper and lower links keeps your pinion pointing towards the transfer case. And shorter upper links keeps your caster even? I found it to be the other way arround when i designed my suspension?
    Also, With the pinion pointing towars the transfer case all the time you would need a double cardan drive shaft to avoid phasing. And that would be a week link in Your driveline

    • @ShawnMc749
      @ShawnMc749 7 лет назад +3

      Double cardan is far better than your other options, like a slip yoke driveshaft.
      Equal length bars essentially acts like a radius arm you see on most cheap long arm kits. Your caster changes in relation to your single pivot point (the frame mount) but your differential will always be pointing at the transfer case keeping your double cardan in it's optimal position where everything is still spinning smooth. Radius arms are cheap and effective for weekend warriors, not the rockbouncers these guys usually see. That's where 3-link/4-link/double triangulated 4 link are king.
      With unequal length (shorter upper) your primary pivot point is now the axle side lower control arm joint. As your flex your caster will stay the same (ideal for on road vehicles) but as your suspension cycles down the pinion will no longer point directly at the transfer case. This is where you start to get into issues with the double cardan driveshaft. It's not longer in it's happy place, the U-joints now want to bind being at such an angle.

    Hey I have a question I haven’t been able to find any real direct answers for. I’m building a yz 4 link rear and 3 link front. Trying to buy heim joints. I’ve seen a lot of kits that use 1.25 inch heims. But choked to to 5/8 or even 9/16 bolts. What is the purpose in such a large heim with a small bolt? I’m mostly street driving and slow speed crawling / wheeling. I could buy 3/4 heims and half the price and use the same size bolt? What’s the deal with that

    • @BustedKnuckleVideo
      @BustedKnuckleVideo  4 года назад

      Not sure why people do that, depending on the size and power of your rig 7/8 hiems would be plenty.

    So I’m building my first linked suspension system. Mine is having issues. I’ve tried adjusting castor with no results. All my links are right and my track bar is tight. All my brackets and components are new. The only difference I can see from what you’ve described is my lower control arm angles. They’re steep at about 14 degrees. Would this cause my jeep to wander? What reaction do you usually get out of a suspension with too steep of lower control arms?

    Don't you generally want to keep the pinion angle parallel to the transmission instead of pointing to the transmission? Then the opposing U-joints cancel out vibration.

  • @bobpayne7419
    @bobpayne7419 8 лет назад

    How about a video on axle tube/steering knuckle removal and reinstallation. Just thinking, when front axle, ie. Dana 44 is lifted or rotated to achieve proper pinion angle, caster angle is usually affected in a negative way. This creates bad street manners, wandering, bump steer, etc.. Rotating axle tubes or knuckles to reclaim positive caster angles cures this. A video on proper removal, and reinstall with tips on full welding and an axle truss for added strength would be a great help

      @denali2m4 8 лет назад

      I have the same question. Let me clarify what he is asking. Let's assume we are targeting 45 degrees of triangulation from axle side to frame side. Traditional link brackets come in 22.5 degree angles, or 30 degree for heims. The question is what part of the triangle are you measuring when you say 40 degrees or better? Adding together the axle brackets angles?
      To ask another way, what angles are you running at your axle side brackets? Given the length of links you and other bouncers are running, I am going to assume that my above example of solving for the 3rd angle is correct, otherwise you would have links crossing over each other.
