It's all good, thanks again. Spent the morning looking for related threads and I think I'm going to tackle the reseal myself. If it goes south...it'll be off to the pros. But may as well take a stab at it.
Thanks @jgeoffr and @Godwin, I might just have it rebuilt..that way I know the entire thing will be right. Good to know the part number and assembly numbers too though.
I have this mess. I think the culprit is the seal on the worm assembly. Parts counter tells me it is 90311-36104 and discontinued. Would like to confirm that's an accurate # before I search out an alternative. Searching mud for that part turned up nothing. Thanks!
