Well like the title says, Im coming up on the big 45,000 mile mark. And to this point (other than oil changes) I have done NO maintenance. What do you guys think. Im thinking, tans flush, injector cleaning, and fuel filter.

 

Air filter, cabin filter, differential, grease the zerks, check power steering fluid....umm...that's all I can think of right now.

 

Do the maintence thats in your book

 

Not to change the subject but I was wondering what size motor you had?13.7 @97 thats pretty fast

 

Differential has been opened twice (posi and later gears) so its good. Filter is a K&N, zerks get some greasy loving on the oil changes, The owners manual is very well hiden in one of many boxes.

And cabin filter?

4.8 litters of fuel injected fury. Everyone knows the 4.8 is just as good as the 5.3 if not better.

 

What do you do to the differential,just check it? Where's the cabin filter? I only have about 8k so far.

 

Id say just check the level in the differential. The cabin filter , look under the dash on the passanger side floorboard. There is a black cover with 3 boltsw holding it on. Take the cover off and youll see panel to the left. Take it off and there are the cabin filters. Unless you are in a dusty environment the filter is probably good @ 8K but it wont hurt to change it once and a while.

 

I'd replace the PCV valve if you haven't yet also.
