5.7L 4x4 service

[Ramdan32]

so I am about to move to a new state and am wondering if I should get the truck serviced. I have 77K miles on it and the dealership recommends:

Differential service
Fuel system flush
Coolant system flush
Tune up

I just changed my oil and rotated my tires (putting new in when I get there!)

My question is since the truck is running fine should I even bother or is this something that needs to get done?

I would do the coolant flush. The rest I personally wouldn't worry with till 100k. YMMV

 

[CincyCuda68]

I would do coolant and difs but I usually have the diff, tranny, coolant and oil changed at 3k to make sure anything left over from manufacturing is gone.

Do the differentials man. It’s easy easy easy. Use premium diff fluid

 

[misfit77]

My dealer suggested a diffy change around 65k.

I pointed out the manual says otherwise. I think 100k if you use for hauling or a service vehicle. They gave a lame excuse because I live in zone b...whatever that means.

I would wait until you have moved. This way you can try out out your new dealer. I follow the owners manual for maintenance, not the dealer recommended service schedule.

Hell yeah. This^^^. The dealer can find all kinds of “reasons” for service. I follow the book and usually an over just a bit lol
