F-550 XLT PS SD Suspension Squeaking about to drive me insane!!!

[socalocman03]

Hey all. I have an 06 F550 which just past 60k on the odo. This is a Work truck and is loaded to its max + some 90% of the time. This past week the suspension has started to squeak like a cage of birds as soon as I hit the not so smooth dirt (like an "E" ticket ride at Disneyland) she starts a singing mostly seems to be from the rear but a bit from the front as well.

I know older SDs have Anti-Squeak pads between the leafs in the front but haven't located any information to suggest my 06 having any such inserts for the rear leafs nor the front coils.

I grease every zerk under the truck (not many) at each oil change, spray white lithium grease at points of metal on metal ie where overload leaf contacts the bumper etc...., replaced shocks at 45k with Bilstein's. What am I missing here? Any help, ideas, suggestions or comments are appreciated. Thanks Les

How about your sway bar links? They could be worn.

What's the best way to tell if they are worn beyond there service life? Probably unrelated but did notice today the front tires are starting to wear more on the inside tread of the tire than the outside which I believe is a sign of a toe in condition but not thinking it has any bearing on my squeaking issue?

thanks for the input

When I changed the links on my Excursion I could here them clank and squeek drove my wife nuts, They were pretty bad though, I would just crawl under there grab one and see how much play it has, There should be none (by hand) and see how much they twist and see how bad the rubber looks, You'll be able to tell just by looking at the condition of the rubber straight away. I would also grease between the leafs of the leaf pack or just spray some WD-40 in there and drive it to see if that kinda helps. When I had my lifted F350 the big arched springs would get squeeky & i knew it was time to spray WD-40 in the leafs to quiet her down! Hope that helps.
