Car Wheels are very wobbly

[Richards.D 761]

Hello...

I've read some recent threads about wobbly wheels, and the vehicle I am working on suffers from this issue as well. I have read a few posts on causes, and I don't believe that any of those are effecting my vehicle, so I decided to post here and take a shot at fixing them. At the moment my truck has perfect wheels while turning. The second I move slowly however, and turn they wobble immensely. I don't really see any issues, and I made sure double sure by confirming the location of every single point for my memory and land contact LOD.

From reading some forums, the problem could arise from this sourceAddress:

sourceAddress="loop";

I don't really know why that could be causing it, as that is straight from A confirmed working demo model.

Thank you in advance... Richards

Your axes (axises) are positioned properly?

The skeleton for the wheels has the wheel axes is in the correct order? The axes for the wheels are included in the named selections that turn the wheels right and left?

[alexboy 11]

your Axises are probably diagonal... not leveled correctly.... or you could have moe than 1 axis named the same thing causeing it to not know which axis to really spin around..... happens to me alot.... gotta get the axis Dead center to get the perfect spin and crorrectly leveled with the wheel itself

Alright:

I managed to fix the messed up front wheels that turned. It was an issue with the model.cfg. As for a slight remaining wobble in the tires: I tried to ensure all the pieces were completely lined up, and I got them as close as possible. It still wobbles however.

I'll throw the model up right now for your perusal if you wish to try and find any error:

Disregard the second problem. After hours of frustration, the problem has been discovered. My wheels were modeled incorrectly, and were uneven. Had nothing to do with the axes. So, I have remodeled them and it works like a charm now

[alexboy 11]

make sure u take down that download... incase anyone wants to take the model and make it their own some where else :)... and happy to se your model works better... so it was just the wheel it self that was incorrectly positioned / angled ? if i read this correctly
