  1. Those numbers mean 265/35/19 = 265 mm wide / 35% of that as sidewall (265 x 0.35 = 92.75) / fitted on a 19 inch wheel 19x9.5 = 19 inch wheel diameter and 9.5 inch wheel width v/r Andy
  2. Here are those hubs with the ball adaptors from 8880. This iteration is far better than V1 and should hold up to a great deal of abuse. Basically the same architecture was used in this MOC. With the ball part installed, I can not separate the wheel adaptor from the hub, but removal of the ball may weaken the structure. After all, the ridge that holds the wheel adaptor to the hub is preventing from deflecting by the presence of the ball. v/r Andy
  3. MRP_, The part that Efferman posted is stronger and has a closer pivot than your concept. I have a pair and they 'get-r-done'!! I've even managed to make a training arm IRS with them. v/r Andy
  4. Looks like your're making progress and learning as you go. We patiently await a video of the performance and ruggedness of the design. v/r Andy
  5. After looking at it again, I'm getting a vibe. v/r Andy
  6. What are your thoughts on the wheels? I trying something similar, but working on 4WD. I like the sway bars. Good luck with school, we'll be here when you get back. v/r Andy
  7. I'm sitting in a bar at an airport laughing at your video and getting funny looks. Amazing! v/r Andy
  8. The top part is mounted in single shear while the bottom is in double shear. The spring would be the part on the right and the axle would to the left. In this example, instead of mounting the spring onto the end of a pin, support both side of the spring mount. This will prevent the spring from slipping off of the end of the pin. Here is a pic of what I am talking about on one of my MOCs. hopefully this clear things up. v/r Andy
  9. The manner in which you mount the springs to the axles will cause issues. They are likely to slide of of the pin. I would recommend putting the 'spring axle mounts' in double shear. It also looks like you will have problems with the 9l links popping off of the balls or the ball pins popping out of their location. They should be trapped. v/r Andy
  10. Four links can come in two varieties. Triangulated and non triangulated. Here is a link to some triangulated four links on a Lego rock crawler. (The pics are too big to post here.) The links are of the 9l type with upper links narrowing on the axle and lower links narrowing on the chassis. Non triangulated four links need panhard bars or a watts linkage to center the axle. The suspension in 9398 is a torque arm suspension.
  11. Effe, Thanks for the suggestion. I ordered a set of the drive shafts and the new 8880 style wheel hubs. v/r Andy
  12. Effe, Could you create a 'female universal joint adaptor for piece 2907' with a slide akin to your u-joint with slide parts? This plus the slide part from this This will allow strong telescoping drive shafts and support peculiar lengths. very respectfully, Andy
  13. NICE! Triangulated 4-links are the way to go for extreme articulation.
  14. You can make that truck 4x4, but it won't perform all that well due to the differentials, CV joints, and independent suspension. If it were me, I would craft a 4-link live axle chassis and place that body on top of it, but then I would realize how heavy the body was and where I could remove weight and then I would re-evaluate the gear ratios I needed due to the new lower weight and on and on in a never ending cycle of change. v/r Andy
