Hey All, I just bought a 2006 Land Cruiser with about 110K miles on it. The maintenance records were pretty good with no major issues as far as I saw. I deleted the ACH myself and replaced with 1.5" OME medium kit, new 33" Goodyear wrangler Trailrunners, brake pads, rotors. I have a couple questions on some things that I want to do myself since all of it at a shop would add up to thousands of dollars. -Replace fuel filter ---bought a Fram one, looks easy but wondering if gas pressure is in the lines I have to wrench -Spark Plugs---was thinking of going with Champion Iridium because of the price but have seen mixed reviews. OEM spark plugs are 16 bucks a piece at a shop and come out to 400 bucks with labor included. -PCV Valve---Very Cheap on Rock Auto. Can I trust this valve or is this another OEM necessity -Fluid exchanges---I have change the power steering fluid myself. Shop recommended Transmission fluid replace, trans case gear oil drain and fill, brake fluid drain and fill, coolant drain and fill. Am I missing anything here? -Grease and re torque prop shaft---seems easy enough -T Fittings/Hoses Check --- not familiar with this. What hoses are proned to failure? -Fuel injection service --- Is this necessary and can I do this myself (dont really buy into the stuff they say you can just pour into your gas tank at this point but maybe im wrong) -CV Left Inner Boot grease leak. Been told its a new axle job which makes sense given the labor. I think I could do this myself but also been told its not a big deal until you hear the "pop" noise during a turn I think that is everything Ive read about maintenance along with what a couple of shops have compiled for me including independent and dealership. Is there anything crucial or preventative that im missing here?
