    Please keep us posted on this. I’m holding off on a lift until this issue is solved. Fortunately, 255/85r17 tires fit without having to do anything.

      Will do! Metalcloak arms are inbound, hopefully should be able to eliminate the harmonics by properly adjusting pinion angle! 😊

    Do you think a re-gearing of the axles would eliminate the booming?

      @@RogerCampillo what booming are you referring too? If you mean the harmonic vibration, the pinion angle first needs to be addressed. A re gear may alter the rpm enough on overdrive to reduce or eliminate the harmonics further, but we need to identify the axle and gear set first to be able to swap. I haven’t had the time to reach out further to Ineos to figure it out, may attempt to contact cararro directly.

    You’ll be chasing these harmonics forever with these modified drive shafts and a lift as the entire driveline was engineered to work best with stock components and driveline angles. Decide what the primary purpose is for the rig. Build it as aggressive off-roader with all the mods and deal with the all the compromises that entails or leave it stock and enjoy the versatility it has to offer out of the box.

      The Grenadier is too low for people that actually use it off road , not dirt road driving. My fuel tank and front skid plate will attest to this!

      @@jasoncouch2480 I’d have to disagree brother! I’ve rock crawled it already through some tough stuff, 7/10 maybe, and that’s coming from many years of extreme rock crawling! I hit my fuel tank skid but I did that all the time on my jeep with 40’s too. The goal is to keep it LCOG with good articulation, that’s why I’m excited for the @metalcloak kit that will be coming out soon, then maybe I’ll get 37’s on her with some trimmed fenders! 😆

    • @themaker959
      @themaker959 4 หลายเดือนก่อน +2

      With any lift, the angle of the driveshaft is too drastic. Causes vibrations and premature wear on pinion bearings. It’s a common issue and Ineos is not covering it under warranty.

    • @Bodhigrenadier
      @Bodhigrenadier  4 หลายเดือนก่อน

      @@peterjack233 they are CV boots, which are prone to short life spans and premature failure under high torque loads, articulation, and severe angles. Lifts exacerbate this issue. Pinion bearings and seals can be affected by these angles and potentially from vibrations in the driveline, which usually is not present in an rzeppa type booted cv.

    Sounds more like a driveshaft phasing issue. Need to look at input/output angles. Adjustable front suspension arms to change castor and thus pinion angle may cure this. To understand phasing see this: th-cam.com/video/Idk3BVDVHq4/w-d-xo.htmlsi=FJGD60ztA6ctRpI5

      @@Greg-e7e oh believe me I know all about it. The angles on this car, especially once lifted are pretty severe, hence the DC joints at both ends. It cured the single DC joint vibes and binding but fit not fully eliminate the harmonics. Unfortunately no one makes links yet to adequately adjust pinion angle, the factory arms only have caster bolts. The rumor is metal cloak will be developing links so I’ll definitely be on that wagon 🤙🤙

      Driveshaft design is fairly universal across RWD and 4WD vehicles and can be replaced/upgraded rather easily as long as you measure correctly and use the correct flange and pinion yoke or an adapter.
      Control arms vary greatly in design from vehicle to vehicle depending on suspension design (3 link, 4 link etc.) and requires some careful engineering to prevent binding and allow for best articulation depending on lift and what you’re using the truck for. That said, it’s not rocket science and someone will eventually come out with some adjustable or “castor-correcting” ones now that people are lifting Grenadiers.

    • @Greg-e7e

      The factory driveshafts use CV joints. Usually people upgrade to stronger U jointed driveshafts to cope with increased driveshaft angels from lift and may go to double Cardon (double u joints to minimize overall angle that each u joint operates at). This front driveshaft uses double double cardon joints (1 at each end) so a total of 4 u joints for the driveshaft. Also he built with 1350 u joints which are some of the strongest Spicer makes for a standard driveshaft. I still think the vibes are due to phasing issue due to pinion angle. I’ll wait for a fix before I lift mine.
