    RCooper--welcome to Grand Design's Technical Forum!

    The short answer is no. I'd already swapped out the OEM supplied Westlakes for Goodyear Endurances, but as I've documented in another thread that was purely a "feel good" decision and not one necessarily based on reliable metrics. Changing to the Goodyear definitely was not a requirement for the MORRyde upgrade. MORRyde reinstalled my wheels and tires with no change.

    As mentioned in this thread, though, it was mildly annoying that they didn't reinstall the better-looking OEM wheel nuts.

      Great post, thank you very much. Now that GrandDesign is starting to offer MORryde disc brakes as an option on certain orders, does anyone know if the brakes are reusable if/when I upgrade to IS?

        Thank you for the kind words.

        Regarding disc brakes, yes, MORryde would incorporate them into their IS system so you don't have to buy them again. Give Brian at MORryde a call at @ (574) 293-1581 ext. 1673 to confirm.

          The new disc brake option is not a MORryde product. When MORryde installs the independent suspension system, they use Kodiak brake components. I've seen several instances where pre-installed disc brakes were moved to the MORryde IS when MORryde installs the suspension system, though.

            UPDATE>>>Just got back from Elkhart. Did the IS, disk brakes and 8-lug rims, what a difference! Messed up the kitchen slide while on jacks but Brian called Grand Design who called Lippert, they sent a tech over. Some adjusting and welding and we were off. There was a spacer missing which allowed the slide to tip to far crowning the guide tubes allowing the gears to jump. Alot of great people at GD and LCI and Brian is the awesome!

                Could you please post what type and model RV you have? TT or 5th wheel? howson has a TT and had a slide issue. I would like to know if that is a common denominator.

                  Vonzoog.... We have the same trailer as Howson, a 315RLTS. I think the problem was the trailer was not supported in the middle and was not level. Talked to Brian and our Tech Sergio about it and they were going to try it on a bumper pull that was coming in shortly after us. I think the frames are designed to be supported on the axles and because it is so long (38') it allowed the frame to sag

                    ^^^Thanks for the response. I’m getting the independent suspension by MorRyde in late August and was planning on spending my nights in the RV while It is jacked up in the shop. Was concerned about the slides being out. Appears to be an issue with your unit and not necessarily mine.

                    I understand what you are saying about a TT that is 38 feet long. I have had owners of long TT’s tell me how long my 42 foot Momentum is and I am looking at their overall length with truck completely in front of their TT that has to be as long as I am going down the road. All of that trailer hanging off the rear bumper has to be more of a challenge towing down the highway than my set up. Makes you think That all long TT’s should be pulled by a dually just like the large/heavy 5th wheels. Look out, now I have started a new debate.

                      17 Dec 20 Update: The YouTube Channel Changing Lanes (Chad and Tara) have installed the IS suspension and disc brakes on their Momentum.

                      Of note, it is possible to get the IS installed prior to delivery of a new GD trailer. Watch their video for more information at https://changinglanesrv.com/morryde-...nsion-upgrade/

                        Yep! We did this last spring. Grand Design did a fantastic job coordinating the move to and from MORryde to get the work done prior to shipping to my dealer.

                          Regarding the Timken bearing replacement. There is another company out there that offers a Timken bearing upgrade with their disk brake install. When I asked for details, they told me that they will replace the foreign bearings with Timken bearings, but this does NOT include changing the races in the new rotors. Whenever I change bearings, I always install matching races too.

                          I'm not sure what MorRyde's policy is. But If you go this route, make sure you understand exactly what you're getting with your modification.

                            Jim correct me if I am wrong but if the races have not been used yet, as in no miles on them, why would you need to change the races? They have not been worn into a bearing yet so it should all be good. When you are changing bearings with miles on them yes you need to change the races. I do this as well but without miles on I don't believe you need to change the races as they are not machined pairs from my understanding.

                              I would be very cautious about using bearings from one manufacturer in races from another. They are "supposed to be" manufactured to the same dimensions and tolerances, but a proper fit is more likely with parts from the same source. My thought would be that if you are going to spec premium bearings . . . include the matching races as well.

                                X2 on Rob.

                                Bearings and races must always be replaced in matched (matched by manufacturer) sets. Would be very concerned about a tolerance stack up issue if using bearings and races from different manufacturers. News bearings must always be accompanied with new races.
