  • 930 midboard hub prep

    Grey Mamba was doing his seasonal prep on his Gear One 930 midboard hubs and notice that one CV body was sticking out a hair more than the other. He brought them to me for a tear down and inspection.

    Always a good idea to mark right and left.

    Admittedly I've never prepped a set of Gear One 930 midboards. I've done a shit ton of 934's, just never 930's.

    I was able to use my press and a spare 930 CV body to press out the seal and bearing on the hub. I do this whenever possible to avoid damaging the seals so they can be reused. Both small seals popped out easily in the press. No pics cause I was fingertips to elbows covered in CV and bearing grease.

    Overall the hubs look really good. I'm used to seeing some gouging on the hub face where the bearing seats caused by over-tightening the CV bolts but these aren't nearly as bad as some I've seen.

      Always a fun job, I tore my gear one 930 hubs down a couple times and kept having play in them, finally figured out the spacing was wrong and had to take .025 or so (can’t remember exactly) off the cv body to get them working right.

      we took the material off the body of the cv because at the time gear one was shut down and didn’t want to damage any of the non replaceable parts.

      not sure if it was your post or someone else’s on gd but someone else had to do the same thing to get rid of the oaky in their gear one hubs.

        I'm pretty sure it was fabr on this board that had the same issue. I need to look up that thread and get some tips.

                Got a package from Kartek yesterday with the new bearing and a small tube of NEO HP800 full synthetic wheel bearing grease.

                This is the bearing being replaced-

                  So the inner race was moving around the CV? Or the bearing cage dented? Trying to understand what I'm seeing thx

                    The race hasn't moved that I can see and it looks fine. Not sure how the cage got so many dents in it but maybe from whoever prepped these the last time during removal or installation. One of the CV's has been machined down an RCH so the outside (hub side) bearing just slide right off. The other CV wasn't machined and the bearing had to be gently tapped off.

                        Grey Mamba can do your hubs but I get a cut since I taught him how to do his.

                          Grey Mamba has been to the L.R.S. School of Off-Road Prep before and he had another class last night. It's fun to show someone how to work on their own equipment and I'm glad he was able to get through the LA traffic and valley temps to make it to my house.

                          The outside (or hub side) bearing is slipped over the CV body and pushed down to the hub. The excess grease was wiped off of the CV prior to the next step.

Line up the CV bolt holes and a drop of red Locktite to each hole and run the bolts in. I use my bench vise to hold the hub in place while I torque the CV bolts. I go 30, 40 and final pass at 50 lb/ft. I also spin the hub to make sure it moves freely after each pass. These hubs are done.




                          This was a fun and quick prep job (even though Dave brought them to me like 3 weeks ago). Taking the hubs off makes prepping them much easier, and takes up wayyyy less space in my small shop.

                            Thanks for taking a picture of my good side Jeff.

                            I wanted to learn how to do this and Jeff always has patience to walk me through it. And I encouraged L.R.S. to give the step-by-step photo demonstration because I know there must be others out there who are confused on how these Gear One Midboards go together. Even from reading all the previous write-ups on this, I still hard a hard time conceptualizing how they all fit together.

                            One thing I learned. The red outer seal needed a pretty good thump from a heavy rubber mallet to get seated correctly. But it's strong and can handle it. So don't be shy with it.

                            This is really pretty easy and not nearly as messy as CV prep. Just assemble in the order above.

                            LRS has a trick to pull the outer seal without damaging it. Do tell Jeff.

                              I use my Harbour Freight press to get the seal out clean, and very likely reusable. I place the bearing carrier with the seal face down and use a spare 934 CV body to press the existing CV and seal out. Thought I had some pics of it but can't find them.
