Newbie member here, just picked up a 2001 Le 4x4 for my wife at the Speed's auto auction in Portland, Oregon THIS FEB. 2360 USD with fees, 211000 miles on the clock. So far 4 new tires, 6 Iridium NGK Plugs, LOF with 10w40 Mobil1 High Mileage synthetic , Wix filter from O'Reily parts store, new fuel filter, New Air cleaner, new belts{internet} Drained and changed front and rear differentials[ Rear is LSD}. Vehicle had near new front pads, and rear shoes with new hardware when purchased. Needed a master cylinder, Previous owner put something other than dot 3 in ther and the pedal was mushy to say the least. Went with a rebuilt from O'Reily, used A RESERVIOUR FROM A USED UNIT PURCHASED IN Albany. a GALLON OF Prestone Synthetic Dot 3, flushed out and bled all 4 wheels. A pleasant 3 hours in the garage bonding with the bleeder screws, clear tubing, and a qt mason jar. Figured out the Proportioning valve above the rear axel, and the rear axel went real good. The tire shop quoted 1500.00 to renew all components, gonna drive her now, don't think the foreign fluid went past the first hardline junction which I drained prior to blleding the system. As for the spark plugs, got to practice patience and the ability to bend my fingers into hitherto unknown configurations. I honestly think this was the 3rd set of plugs for this gal, one was not threaded all the way home. they were NGK Platinum, and thankfull all came out clean. .
