I used 80w90 oil. I would buy new washers for it. Have you done the rear Diff? Remember to always pull the fill plug first.

 

The bolts have washers? I haven't done my front or rear yet. I saw a DIY on the vibe forum and plan on following it

 

Yup they have washers. Might be 2 kinds. Go to a Toyota dealer if you can. They will have them

 

You have 4 bolts altogether I forget what ones have washers but I know some do. I'll be doing this in a week or so when my kids bring the car home from college. Remove the filler plugs first then the drain plugs. You'll need a cheap pump.

 

You can go to toyota of cool springs with your vin and look them up and order them.

drain plug washers # 12157-10010

 

Any GL5 90-grade can be used. Plenty of really good GL5 75w90, SAE90, and 80w90's at walmart and local autopart stores. Synthetics are a good upgrade here. 75w110 can also be used.

Toyota typically uses 18mm drain/check/fill plugs. Any copper/aluminum 18mm washer will seal fine. Toyota uses different torques for iron vs aluminum diffs/xfer cases usually in the 27-36 ft lbs range. Toyota typically uses a steal donut crush or flat washer and OE is not required. Match the drain/fill plug sizes to metric copper/aluminum/fiber washers at the local autopart store Dorman/Needa/Help or oil sections. They also typically use 24mm socket or 10mm Allen wrench for their drain/fill plugs. I do recommend a genuine non-imported 10mm Allen hex wrench/socket and 24mm quality sockets. Sometimes these plugs are super tight and cheap hex wrenches will strip out the inside of the Allen plugs, while cheap 12-pt sockets will round out the corners of the 24mm plugs.

I get all of my 'washer-gaskets' and gear oils at the local autopart stores.

Don't neglect the manual or automatic transmission fluid too.

 

I just ordered a 6 piece washer kit for transfer case and diff from Amazon for $10. Vendor was APSZone

My preference is to order online. It's easier and quicker for me. I have some Valvoline GL5 80w90 left over from my ford ranger. I'm going to use that.

 

I did a drain and fill on the TC and rear Diff yesterday. I had ordered a washer kit off amazon. It's pretty easy. I used Valvoline 80w90. The oil in there was not horrible. I've done it about every 4k Miles or so. Since I bought the car in 2009 wuth 100k on it. Use car ramps on the rear for the diff and car ramps on the front for the TC. I clean all the grease up while I am there. I use brake clean, simple green, wire brush, garden hose, etc.

You'll need a cheap $10 pump. When you pull the plugs look closely you should have a crush washer on most. Pull it off and clean plug, install new washer on plug.

 

How many quarts of oil did you use? What pump did you use? I'm assuming a hand pump like on a bottle of lotion. If so didn't your hands get tired from pumping?
