To install the mud flaps, you simply remove the stock plastic grommets that hold the fender wheel liner in place, position the mud flap and press-in our longer plastic grommets into the existing holes. On the rear there is one bolt to remove the mud flaps from under the car on newer Model Y's, but you place the same OEM bolt back in to secure the mud flaps. Super easy!
Front Mud Flap Adjustment: Some front fender liners are not assembled the same way as others. If you have a gap between the front mud flap and the fender liner, please check the Front Mud Flap Adjustment videos on how to remove them.
Just place the rear mud flap in place and locate the downward facing bolt just under the back fender liner. The bolt will be covered by the mud flap's plastic tab so you can identify it.
Then just unscrew the bolt, but as you unscrew the bolt, If you feel the tension increasing we suggest you use lubricating oil on the threads to insure you do not break the nut from the welded location on the metal frame. There is a new video on the above tab labeled HELP and here is a LINK.
Once you have the bolt screwed back in and you have placed the mud flap, do not over tighten the bolt or you can crack the plastic tab. This will hold the mud flap in place better than the plastic grommet.
To install the front mud flaps, you simply remove the stock plastic grommets that hold the fender wheel liner in place, positions the mud flap and press in our longer plastic grommets into the existing holes. For the back wheels you use one of TESLA's existing bolts in the lower plastic hole.
