120K maintenance

I'm at 122K now on my 3.6 and it looks like I need to change the auto transmision fluid and differential along with an oil change and air filter. I got the spark plugs changed at 100K, so that is done.

The manual says to also inspect some of the front suspension and brakes. I got my brakes worked on a while back, but don't remeber exactly when.

From what Iv'e read, the coolants doesnt need to be changed until 150K.

Anything else you guys would reccomend?

At 120,000 both axels need fluid changed, Transfor case and transmission too. Big $. The transmission fulid is $37. a quart and very few plaves is any can change the fluid and not mix is up with the other brands of transmission fluids. My dealer wants $350 for the trans, $ for each axel and $139. for the trasfor case. I just had brakes at 110,500. they still had 7mm left.

I didnt think it would be that expensive. i have a 2WD though, so i wont need as much.

Tangent, I would change the coolant even though it’s a bit early. I like doing things a bit early.

Your language suggests (to me) you are going to have these performed by someone else?

If you take it to the dealer you'll pay more, but then you're assurred they'll be using the right fluids. And they would log the work on the service records (which could be of financial benefit when you sell it). Most of the fluids they use these days are synthetic, which is one reason they last as long ...but then you don't have to change them as often either. I guess if a guy figures ..replacing conventional fluids 3x (by now) at the old-days price, it would be about the same or more (if the dealer did it). nex

The word on the street is a regular cab short box isn't available for 2023, so if you were thinking of trading to newer, next year, you might want to pull it forward to ..soon.

I personally do my own. Synthetic gear lube at Walmart is like $12/qt (takes two), and I get tranny fluid from my small town chrysler dealer (out of their bulk barrel) ...just take in my own milk jugs. Actually they have a stack of clean milk jugs in the corner of the parts dept everyone brings in LOL. It's funny. The dealer sells it cheaper than I can buy it anywhere else. But if I go to the larger city nearby, they jack the price up and it's no bargain (they won't sell from the barrel). But you can buy it online. What transmission does your truck have? 6-spd or 8-spd? I wouldn't change the 8-spd tranny fluid unless you have some tranny fluid changing experience. And plus, it's a really messy job.

If you're not a DIY guy, just take it to the dealer rather than put it off. So what if it's a little more $$. You've got a wonderful truck, and it looks great. Repairs from bargain-work screw-ups aren't cheap either!! LOL
