Fluid Flushes.. Please help clarify!

Hey guys, I have recently posted about this sort of stuff, but wanted to finalize and get it all laid out. After coming back from toyota the other day, they basically said all my fluids need replacing... Dont know when they had been done last - maybe never (Im at 166K miles). I just want to make sure I will be using the right fluids for the job and how much of each to buy.

Tranny Flush (Amount: 14 qts):Either Redline D6, Toyota WS, or Valvoline Max Life ATF. (Any other possibilities?)

Front/Rear differentials & transfer case (Amount: 6qts): Mobil 1 full syn.

$30 75W-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75W-90 gear oil

Power steering flush (amount: ??3 qts??): Valvoline dex/merc? (Any others? I really have no idea on this one because I have heard people argue everything under the sun.. Lemme know what you guys have used and if it works as it should..

Brake Line Flush (How much fluid to buy?) Also havent researched this one much yet but any info would be appreciated.

In addition to these tasks I need to complete, I also get to re-seal leaky timing chain cover, replace front drivers wheel bearing/hub assembly, get a new battery, clean and adjust rear brakes. Just keeps adding up. How much is too much as to where I should just sell and buy a newer truck? And how long can a leaky timing chain cover go before any catastrophic issues start to happen?

I know this is alot of questions, but if anyone can lend some advice and help me finalize all of this that would be GREATLY appreciated!

 

Bump

 

I used 2 quarts when I replace my rack
brake fluid maybe a quart

wheel bearing on ebay for 100 bucks or guy on here sells them for 175

timing cover leak could go on for years or start to leak really bad in a day

 

do all the gear boxes first.........motor oil......G O O D filter !! SYN !!!!

worry about PS.....cooling later.......

someone will chime in

 

As far as selling and buying new.......

Your list includes a lot of ignored routine maintenance, along with some normal repairs. If you will keep up with things it won't seem so overwhelming in the future.

As far as the trans goes. I'd do multiple drain and fills. You'll eventually consume that much fluid, but doing an actual flush/ fill as you propose isn't really a driveway task.

 

I'd recommend getting at least an extra quart of the 75w90 gear oil to flush your diffs and tcase with after draining. If they have really never been changed then there's probably some gunk in there that you might be able to dislodge with some flushing.

 

Awesome thanks man. I think Im going to get the dorman wheel bearing/hub from rock auto. I dont want to send too much on the other ones even though they are better.. Lots to do for the truck in the coming future so trying to save as much money possible.

 

Caution. Some things are pay once, cry once. Some cheap parts are fine. Ones with little labor and risk of leaving you stranded.

Some items deserve your full attention.

 

Youre totally right. I bought the truck from a dealer used figuring they would have atleast changed all the fluids... I suppose ignorance on my part.. All other routine maintenance is done at regular intervals. Once I do all of this, everything will be done regularly again.

For the trans, wont doing multiple drain and refills just mix in the old with the new and to get it completely clean would need twice as much fluid? I was thinking of doing the trans flush per the tutorial on TW. Seems like something I could do in the garage. Just curious as to why this wouldnt be a driveway task?

 

So basically drain-refill-drive a bit-drain-refill? I was going to get 6 quarts for both differentials and transfer case. I guess I should get more like 8 in order to flush?

 

True. Ive heard people on here saying that the dormans have actually lasted them a long time.. Others less. I would take the time to rebuild the assembly, but when pricing out, it was more expensive than the new complete assembly itself. $175 for the bearings by bamatoy or the other dude that sells them on here just seems expensive. Not sure what to do. Id rather get the TW assembly's but all this is adding up to be pretty spendy.

 

No just drain completely then use a hand pump to forcibly squirt new oil into the empty diff/tcase for a few good pumps. After the pumped oil drains then plug and fill to appropriate levels. That oil is going to smell like liquid death if it hasn't been changed in over 100k miles.

 

Do you think that just a few forcible pumps will really do much? Just rinsing the gears of some metal particles? And does a few pumps mean about 1/4 quart or less?

 

Also, for the t case and diffs, do you just refill til they overflow and plug em back up? Or is there a certain amount of oil needed for each?

 

I think it will help a little. Most of the metal shavings should be held by the magnet on your drain plug, but pumping might dislodge some of the thicker burned oil.

 

Yes all 3 have a set amount of oil to use, but you can stop as soon as you see the new oil start to dribble out of the fill plug.

 

Don't overthink it, just drain and fill. It's easy, and stinky, but saves lots of money by DIY. Plenty of good 'how to' info on the the web.

 

No one should be taking their trucks to the dealership for these fluid changes.

 

Thats exactly my problem sometimes. Im just guna go for it and it should all go well hopefully.

 

Totally agree! They wanted $66 per diff and didnt even quote the T case. Tranny Flush $245 and PS flush was another hundred or so. Rediculous if you ask me. I always like to do this kind of stuff myself when I can. I just like to do thorough research before I start. Thanks for all your help!
