I wish I'd gone ahead and just changed those and not the rest of the job, although I don't suppose it will hurt anything.

Mine was whistling, too, but I thought it was the center case o-ring.

Oh well, new receiver dryer tomorrow and I should be done with it.

Now I have a clunk in the rear when I put it in reverse. Always something....
