No way am I an auto mechanic. 59 years old. But with you tube I've been doing a bit myself with prices being the way they are. Dealership wanted $383.00 to tune my 07 titan,[8 spark plugs]. Since then I try to do what I can, brakes, all fluid changes, from oil to differentials to transfer case and so on. This includes our 08 jeep cherokee and 01 tribute. You tube has been a blessing for me, with the high pricing, then a manager saying I need this and that, after having same work done within the past year. Chrysler dealership always tries to kill me, 08 jeep has lifetime drivetrain warranty, so I do get certain things done by them, transmission flush, coolant flush, and their tune up[$69.00]. I always tell them to check the records. Just did front and back brakes,rotor and pads on the titan. Was a fairly easy job, other then the tires being placed back on. Thank you you tube.
