last weekend after i fixed the starter in the truck ( or rather cleaned the wire and put it back on the terminal). i head a really bad squeak and chirp comming from one of the pully's. Is there a way to ind out which one it is without removing the serp?
while looking for some sort of simple remedy someone told me to douse the pullies in WD and see if it goes away, so i did and it didn't.. now im slightly worried about the wd eating the rubber... should i be?

Another thing i cant seem to figure out isthe proper torque for the lug nuts. the haynes says somewhere between 100 and 145... now is that because anywhere in the range is good or is that a difference between the F150 and the bronco ( as i suppose you know the haynes for our trucks covers both the F150 and the bronco) it also makes reference to different lug nut sizes.
this confused me and i quickly found out the all the lug nuts on my truck are different sizes ID is the same but the outer dia ranges. am i correct in assuming this is due to the previous owner just using random lugs...? where can i get a complete set?

I am about to tackle the replacement of my driverside e-brake cable, i was told it is simple and only a few nuts.. any words of wisdome for me before i take it out for a spin?

Im in Fort McMurray alberta and the only real parts stores i know that i have at my fingertips is cambodian tire and NAPA... the junk yard guy out here is off his rocker. (the interior dome light cover for a single cab-$25, i simply laughed and walked out...

as always, any advice is nice...

 

I don't know about the affect of WD-40 on the belt - it'll probably burn off quickly anyway. At your NAPA store, you can get belt dressing specifically for the serp belt.

For the bearing noise on your pulleys - I would pull the belt and spin each one. It's not nearly as bad as you think. Get a big break-over bar on the idler pulley nut, and give it a twist (it's reverse threaded, so you can pry the pulley up without loosening the nut). While it's up, slip the belt off. The idler pulley is probably the culprit, but it could be any of them.

If you'd rather not pull the belt off, try some silicon spray - spray the bearing area of each pulley one at a time and see if the noise goes away.

I don't know about torque specs on the lug bolts - I just get 'em tight and check again a week or so later. Different sizes are thanks to a previous owner - you can buy a complete set at NAPA.

E-brake cable is simple - the hard part will be breaking the old nuts loose. Use some PB Blaster or other penetrating oil for a few days before you're ready to take it apart. While you're under there spraying, just give it a good look - it's a fairly simple setup.

 

Make a stethescope out of a length of hose. One end to your ear and the other use to search around until you hear the squeek. The WD won't hurt the belt, as long as you don't spray it regularly with it. Anywhere between 100-145 is fine for the lug nuts, although I don't bother torqueing them. While the book gives you torque specs for most everything, most everything doesn't have to be torqued exactly. Just things like bearing caps, heads, intakes, etc. Most parts stores will sell sets of lug nuts, although matching sets aren't necessary as long as they have the correct seat.
