My Rancher 4x4 has about 140 miles on it now and I have yet to have my 100 mile tune up because I dont have a trailer to take it to the dealer. Most of those miles came above 20-25 mph. Just wondering how strick I should be on that 100 mile tune up. Should I park the thing until I can get it in, or just not worry about it and take it in when I can?

I also won a warn 424 off of Ebay. I'm eagerly awaiting it's arrival. Trying to decide if I should install it myself or have the dealer do it during the 100 mile maintenance.

 

If you can handle a wrench you can do it yourself and probably save $100-$200.
You can also change your oil and filter and check the valve clearance yourself. Look for a shop manual on e-bay.
