Got a questions for people that have had the E10 a while.

While having a first drive outside (the weather has been poor).
I noticed the car grounds a lot on my flagged drive.

I lifted the body up, as high as the pegs adjust.
But still seemed to get some scape...

Noticed its marking the underside of the chassis as well.

Anyway, I have also noticed the wheels seem to wobble a little.
I thought at first the wheel screws may have been loose, but they are not.

I can hold a wheel and it moves a couple of mm. After checking, all the wheels do this, and it seems to be the round block the wheels are fastened to? Not sure what its called, but the drive part goes through it. May be a knuckle?

Are they supposed to be a little loose and wobbly?

I am fairly new to this hobby, so still learning.
None of my other RC vehicles are like this.

Many thanks in advance,
Drew
