A little Help/Changing My Fluids

[DuckHunter]

I recentley returned home from afganistan i am from arkansas, Currently stationed at Ft Hood Tx. So after i took alittle time off it was time to make the trip back in the yukon. 683 miles to be exzact. It ran really well until about 200 miles out from my destination. Fuel pump went bad had to leave it at a local shop where they replaced it and picked it up the next day $580 repair. Monday i notice that there is alot of grease on my front left inner fender. After looking at it for a few i noticed that the cv boot is busted so bought a new axle shaft from advanced auto currentley waiting for it to be installed. She now has 234000 miles. I know it is time to change the fluids. My plan is to flush and replace tranny fluid filter, radiator, brake fluids. Are there any more? Can i do any of these easiley? My next step is to start saving for a new motor and tranny i know its coming soon. Both seem to be holding strong(knock on wood) But hopefully these is not a trend of things to come. I do not want to be constantly replacing things. Yes i do know it is a very high mileage vechile just havent decided to sell or keep it, it is paid for and my only means of transportation rightnow except for my wifes cars she is back in arkansas currentley in school. I do really like it so i guess ill try to hold on to it for awhile longer. Any help and thoughts would be helpfult thanks I attached a few pics of what it currentley looks like

Out of the 234k Miles Has any of the fluids been changed before? You can change the front diff, rear diff, power steering, radiator in no time easy to do. The problem is the tranny be careful changing the fluid at that high of mileage especially if it hasn't been changed before.

You also stated saving money on a new motor and tranny why dont you save your money sell what you have and put it towards a newer model with lower mileage.

Are you able to do the mechanical work yourself or are you going to pay someone? That's another reason to be careful with a high mileage vehicle, if you can do it yourself then great but if you need to pay someone every time something goes wrong you will be in the truck more then you want to.

Do a search on this forum, google and youtube you will see a lot of instructions on how to change the fluids on your truck.

best of luck!

Here is the link for how I changed the coolant and another link to the way to change the transmission fluid by letting the truck pump it out. It was the most recommended way to do it for high mileage engines. I've heard a lot about not having the tranny flushed because it dislodges too much stuff and can cause slippage. It worked great for me. Just make sure if you use the dexcool that you pre-dilute it. Don't put straight dexcool in, then add water and let it mix itself in the engine.

When you change the transfer case fluid, I would suggest going to the dealer, and buying new drain and fill plugs. It's worth the extra $8. I was glad I did. I found that after years of quick oil change places, the fill plug was pretty rounded out.

Depending on your truck, it may or may not have a rear differential plug to drain the oil. If not, you have to remove the cover.

Thanks for the help and advice. Iam not very mechanically inclined but think I could handle changing most of the fluids there seem to be a lot of how too's on it. I recently had a son and soon will be getting out of the army i would really like to upgrade but not looking for another payment what I'd make of mine would put Me in a somewhat lower mileage vechile than I already have. I had it forsale for awhile but people offered trades seems no one has cash these days. I'd rather just stick with mine atleast I know what's been done and what needs to be done. It currently has 223858 Lil off on the first post. It's been a great vechile would like to upgrade eventually but now is not a good time between a new edition to the fam purchasing a home would be nice though would really hate to see it go though

I flushed my transmission last weekend using the method in that link. It worked great and it`s very easy. The hard part is in dropping the trans pan. I couldn`t remove the #40 torx bolts that hold the shift linkage on for anything so i gave up and just bent the bracket out of the way. It doesn`t need to be bent back, it shifts fine with the bend.

I have no idea why anyone would use a torx bolt on anything. If it had a regular bolt the job would be quick and easy.

Sasquatch - I had the same issue with the tranny linkage. What a joke who ever designed it like that. I bent it out of the way but I bent it back. Worked fine for me as well!!

I need to do my front and rear differential, and change it to synthetic, any do's and don't recommendations?

I need to do my front and rear differential, and change it to synthetic, any do's and don't recommendations?

I changed to royal purple synthetic in my diffs. They use 75-90 and the Front takes 1.8 quarts and the rear 2.75 quarts.

The front is very easy, Just drain from the lower plug and fill from the upper plug.

The rear isn`t hard at all. The diff cover is close to the sway bar and if you use a bead of silicone instead of a gasket you just have to be careful guiding the cover past the swaybar so you don`t mess up the silicone.
