Is there anything special i should be doing to my blazer when it hits 90,000 miles? I am due for an oil change in about 900 miles and i just passed inspection for this year, new K&N air filter, i know i need a new battery and tires...as far as maintanance is there anything else i need to do to my blazer??..what kind of battery should i get by the way?? and i know i will be getting Uniroyal Cross Country tires set of 4...thanks for the help!!!

 

Service the diffs, t case, transmission.

 

In addition to the above, I would do plugs, caps, rotors, chassis lubrication if it's been a few thousand miles since last, check belt, check brakes, that's off the top of my head. No need to upgrade your battery for a bigger/powerful one really, unless you like to run your stereo with the blazer off.

 

Yeah i do need to service my differentials both the front and rear diffs...chassie lube is not a bad idea, i already had my plugs,wires, rotor, cap and belts and hoses all replaced with new ones...yes i do run heavy car audio so i do need like a deep cell, like an optima yellow top or something..thats the only one i know that comes in a group 75 size...thanks
