Hello all. I am sorry if this isn't the right place to post, but I have issue and would like to see if there's a way to fix it.

Recently I have decided to set up some driving game real quick (just for myself), came across 3-4 tutorials and car samples, but none worked good for A7. So I followed up some YouTube video tutorial and got it almost done.. except for this



The wheels aren't going as supposed... but doing it sideways (resulting in crazy jumping and flying). Any idea where's the fault? Not sure if it's wheel model axis related.

The wdl script I used (just slightly edited, came from that tutorial): http://pastebin.com/cWhGmDRm

Thanks a lot in advance!
