107k - what fluids would YOU change?

2007 SEL AWD. Other than engine oil & coolant - they are done. What about the tranny and the diff? Power steering and brake fluid? Thoughts? Thanks!!

Tranny and brake fluid for sure. Power steering is easy.

Thanks. Power steering - just a turkey baster and remove fluid and replace until it runs clear?

[akirby]

Pretty much. I would just get out as much as possible with the baster and replace it. Be sure to move the steering lock to lock a few times to get out any bubbles.

 

It's not hygroscopic like brake fluid.

I would change the ptu fluid, rear diff, transmission, and the brake fluid.

 

Note, when changing the ptu fluid you will have to do a flush type service by sucking as much fluid as you can from the fill hole and then filling it up with new fluid until it spills out and then rotate the front wheels by hand(need helper) and then suck out the fluid again and fill it up with new fluid again.

 

You will have to do it about five times to completely flush the ptu of old fluid.

 

However, the best method to remove all the old ptu fluid is to remove the ptu and let the old fluid drain out all at once.

 

The same for the rear differential fluid, except with the rear diff you will get all the old fluid out when you remove the differential cover as opposed to trying to suck the old fluid out of the fill hole.

 

The brake and transmission fluid changes are a pretty standard service like any other car.
