I don't think so, I'll check tomorrow. Would the military put those in? And for what reason?
Yes, they do put those in or remove when they align the vehicle for certain requirement.......up armorer......troop carrier only..... or change from bias to radial tires......
See section 7, Alignment Procedures......in the AM General Corp book.....Military HUMVEE......page 7-17
Technical name for those "shims" are Spacer Plate..... .060" and .120"
TM 9-2320-208-24P-1........pictured in figure 181 item 5.........and figure 184 item 9
Any changes to this will effect toe-in and toe-out in both the front and rear suspension units which ever unit you changed the geometry on......
Also one would be advised to also check vehicle tracking......
