What did u have to do to fix the front and rear problems??

[@griffsminircdrift]

Hi! I hope this helps
Front:
- Upper arm: The goal the arms must move freely up and down without having back and forth movement. I've added a 3rd shim to both side, but because the arms didn't moved freely I've sanded them to be a bit thinner. (Do it in multiple iteration, don't sand to much at once.)
- ball joint: Check if the ball caps moving freely on the ball heads without the threads. If no, try to apply some pressure on them with a flat pliers (smooth surface) until they are moving freely (multiple iteration, don't apply too much pressure at once). Assemble the ball caps with the threads. Check if the assembled pieces are moving freely on the ball heads. Yes -> Good. No: Try to deepen the holes. If the joints still don't move freely. You can sand/cut from the ends of the threads to reduce the tension caused by them on the ball heads.
- sliding rack: The goal the stearing plate should move freely but it should not have back and forth play. The steering plate holder should be thighten in the correct position to achieve this.
Rear:
My setup is not default. I am using the optional adjustable rear arms to achieve wider setup. (In the current setup it adds +2mm to each side.) I'm using 3mm longer CVDs (13.5mm). This causing me problem if the angle between the CVD and horizontal plane is too big than the wheels are not rotating smootly because diff cap strain the CVDs in some positions.
