Like the title says I am about to roll over 50,000 miles. What should I do as far as tune-up/maintenance. The logs in the book stop afte some initial maintenance stuff. Should I do tranny/diff/spark plugs? Thanks.

 

oil/tranny/diff fluid/air filters

Spark plugs should be fine till 100K

 

Exactly what I was about to suggest.

 

Honestly I'd replace the spark plugs now. Not too expensive, easy to do, and they will be pretty worn by the time they hit 100k.

 

oil should done every 3k miles.

change everything you can think of as in fluids and filter:

radiator
tranny
diff
air filter and
a/c filter

spark plugs, i change them mine out at 35k because of the dd that i do but its up to you... my next change will be at 70k. then 100k.

also, check your belts and hoses. small and big ones. im almost to 50k myself so ill need to do the belt and hoses myself since im going to change radiator fluid. just an suggestion...

 

I believe the manual says otherwise.

 

yea but thats the unwritten rule. i personally change my oil at 4k. anyone have a problem with it? you wanna start a fight? huh? lol hopefully it doesnt spark up a "how many miles until an oil change" thread.
