LML is over 60k now and it is needing an oil change, I don't have the book here and the truck is out on the road. I would like to have all the service materials on hand when it returns and unhooks it will be turing around and leaving with another trailer that day so I need to be quick

My question is for the LML what is recommended to be serviced at 60k? Obviously it will get oil and filter and fuel filter as they are due anyway. Is the trans needing anything? transfer? axles? coolant?

Thanks

I can't speak for now but back in 1998 when we bought 2 new farm pickups, the book said to change the axle oil at 35k if I remember right.

If it were me being its seeing some heavy loaded miles I would change the oil in the front diff, rear axle, transfer case, and new allison spin on filter. If the oil from the allison looks questionable when changing filters I could see if you can send it in to get tested. Your coolant should be fine, just look at it to make sure it doesn't look terrible.

I'm no expert Jordan so I hope others comment so you get second opinions, haha.

Thanks man, yeah I am just not sure anymore on the new trucks. I typically wait till 70k on axles on the newer trucks, but this lml is seeing huge loads now. we may have gone a bit too big on the new trailer, but till the lml has no issues with power but its suspension is possibly having issues by looking at tire wear.

I wish I had the book to look, I would call my sister and sask her to read the book to me on recommended service but I don't think she understands that stuff

Well there is a a 40 and 80 thousands service. But I will let you read it yourself :frog:


First Engine Oil Change After
Every 40 000 km/25,000 Miles
. Pickup Models: Automatic
transmission fluid and external
filter change (severe service)
for vehicles mainly driven in
heavy city traffic in hot weather,
in hilly or mountainous terrain,
when frequently towing a
trailer, or used for taxi, police,
or delivery service. See
Automatic Transmission Fluid on
page 10‑11.
. Four‐wheel drive pickup models
only: Transfer case fluid change
(extreme duty service) for
vehicles mainly driven off‐road
in four‐wheel drive. Vehicles
used for farming, mining,
forestry, Department of Natural
Resources (DNR), and snow
plowing occupations meet this
definition. Check vent hose at
transfer case for kinks and
proper installation. Check to be
sure vent hose is unobstructed,
clear, and free of debris. During
any maintenance, if a power
washer is used to clean mud
and dirt from the underbody,
care should be taken to not
directly spray the transfer case
output seals. High pressure
water can overcome the seals
and contaminate the transfer
case fluid. Contaminated fluid
will decrease the life of the
transfer case and should be
replaced.
First Engine Oil Change After
Every 80 000 km/50,000 Miles
. Engine air cleaner filter
replacement. See Engine Air
Cleaner/Filter on page 10‑17.
. Pickup Models: Automatic
transmission fluid and filter
change (normal service).
See Automatic Transmission
Fluid on page 10‑11.
. Van Models: Automatic
transmission fluid and filter
change (severe service) for
vehicles mainly driven in heavy
city traffic in hot weather, in

My thinking is if you are seeing severe duty like that, you should shorten your maintenance intervals to match. Those fluids are certainly cheaper than replacing broken/worn out parts. Russ pretty much hit on everything I would look at.
I'd treat constant heavy towing similar to a drag racing or sled pulling schedule.

I change the oil at 5k transfer and diffs every 15k, trans filter @5k and fluid at 30k. Brake fluid and hydro boost every 2 years. Air filter every other year and AD and CAT fuel filters every 6k

Got her all done, I did let the dealer do a trans flush on it and the transfer and axles, I had to leave in a hurry to come up to Michigan for a family thing, so all I did was oil and filter and fuel filter and greased the front end, the truck did have both upper ball joints bad so I put those in also.

We have got to get the weight transferred off the front end better. I have air bags coming so that should help.

Our maintenance is typically top notch, but this truck has been on the road so much lately I haven't had time to keep up.
