Thanks funkster, I was ready to take out my liners and remove the mud flaps.

 

Does this TSB include both Style and Flaresides? I've beed following this thread and still not sure which box/bed style it's refered to? Help?

BTW: FLARES RULE!!!!

------------------
99 4x4 XLT supercab 5.4L Flareside, Deep Wedgewood Blue/Med. Graphite w/Captain Chairs, Pioneer DEP-4000, Tint, K&N, Bedliner, 3" Catback w/3 Chamber Flowmaster, Superchip, 285/75/16 BFG A/T on American Racing Python wheels, Stull Billet Grill, Clear Corner Lenses.

'00 Expedition XLT, Silver w/Dark graphite interior, 5.4L, Stull Billet Grill, 2/4 Drop and some other stuff. All in all she'll stay stock. Ok, maybe a Flowmaster 50 series soon.

 

If the liners are only put on to prevent (MORE) dents, they would not apply to the Flaresides because they are fiberglass and shouldn't dent.
Good Luck.

 

Thx J-C!

 

Try another dealer!

 

Here in Michigan, many early 90's F150's, all with the rear liners, have rusted fenders. Those liners might catch the mud, but slush and salt get up on top of them. Probably can't spray out the trapped salt as easy, causing rust. I guess you could take the liners out for cleaning, but I'm guessing no one does. Something to think about.
