Does someone know how to remove the plastic shield between the wheel-well and the engine-space (right above the control arm, just ahead of the driveshaft).

It seems like its fasten in two points (upper part, the lower part is just loose) but I canīt see any fastening details.

Its an 2001 Elantra...

 

It ought to be the "grided" sheat in the upper left corner of this picture

 

2 bolts hold it to the frame rail... sometimes 3 on the older production.

Need a short 10mm socket and long extension works best
