Some mod is conflicting with the Hopper

Hello guys,

I have a lot of mods. Way too much. Now I don't know which one is causing this peculiar problem. To describe this problem: The front wheels of the hopper is the normal wheels (as to be expected of the Hopper), while the rear wheels look like that of some sports car:

Do you think you can help me if you have the time?

Here:

The config is not modded in any way, the config is just the XT-6 with the color being that of the ETK Transporter T4 euro van Automation mod.

 

I think it is from the Dodge Charger mod
