If no oil comes out when you remove fill plug then remove the drain plug and capture the amount of oil from the transfer case. The transfer case holds just over one quart of oil. With the car, level replaces with new gear oil until the gear oil starts to come out of the fill hole. Repeat in a couple of months to see how much oil is leaking. You could try to find a shop that will rent a lift. I go to a DIY shop that rents lift at $18/hour and they usually include tools and a mechanic to help. This shop is also my indie mechanic who charge $70/hour.
yes; im sure that its not ps fluid; as both shops(the one that actually replaced the ps hose and a different shop that i usually go to) confirmed its the front transfer case that is seeping; the one on a rx350 thats right near the ps pump. its i believe down and slightly to the left i think of the ps pump when u are looking up at the ps pump from underneath. Plus the excess ps fluid that went all over was cleaned up.

Better do a little research on the shop. Use Yelp it can help. If it was my car I would have a mechanic drain and refill with fresh gear oil along with new crush washer for drain and fill plug. I purchased a Honda where the previous owner (or his mechanic) tries to reuse a crush washer for the transmission. He saw that it was leaking and tried to seal it with clear caulk. When I purchased the car I saw that it leaking transmission fluid for the CVT transmission. Drain the transmission, removed the caulk and purchased a new crush washer. It hasn't leaked in three years and I still drive it today.

forget it! I think at this point I’m looking towards a 3rd gen that has been thoroughly inspected by a Lexus dealer that doesn’t have high mileage to start with.

The issue on our RX that I was referring to is the same as the TSB below .... pretty well known and costly repair (~11 hours labor).

Looks like they are trying to up sell you the bearings.
Toyota t-cases are close to bulletproof.
If they werent making noise even with the leak, why worry?
As long as there is fluid in it, those bearings will be fine.
But if you’ve already made up your mind, do what makes you satisfied.
Whatever path you go, you will spend no matter what to maintain or repair ANY vehicle.

Goodluck.

Your transfer case does not need new bearings unless it is making a whining "supercharger" sound. You purchased a over decade old car its going to need to work, grab some tools watch YouTube research and do it yourself.

My guess, the shop that talked about bearings is wrong. It will end up being something where a competent shop will install the new seal, button up the front transfer case and you will be good to go ... still pricey, but nothing near what you were quoted. Find a reputable independent that specializes in Toyota/Lexus and ask them to take a look.

i honestly don’t think it will matter at this point. Even if a independent shop looks at it I can just about guarantee u that it’s gonna be well over 1000 to do the reseal because again it requires that the whole effing trans has to be taken out just to get the transfer case out. And I dont have that kinda money!.

Read through this thread and few others, I've got a leak in my front diff and it's where the front cover is so the shop is planning on taking the transfer case out and resealing it. Only issue is that they're quoting ~19 hours/$2800 to do the job, which seems exceptionally high based on the replies I've seen in this thread. Labor rate for shop is $145/hour. That seem about right to you guys or should I take it to another indy?

The Toyota independent I use charged ~$1500 to replace the front cover; $2800 seems pretty high. I would definitely call around and look for a shop that specializes in Toyota.

If your transfer case is seeping, swap out the oil for a little heavier oil, use a 90/140 vs a 75/90.....Check it every so often.

$145/hour seems kinda high. Really depends on their location, thou....

$1500. sounds like a good price if they dropped the engine/cradle assembly...If they jacked the motor up, then that seems a little high....Really depends on how they did it..It is a tight fit thou....
