Air filters and U-joints

[POLARIS13]

Hello everybody,
1.) I need a new air filter for my wheeler....but before i do, does anybody on here know or prefer a filter set up for my 2009 800 EFI HO instead of factory.

2.) Are the u-joints on any wheeler all the same!? or are some different!? i am needing some for my prop shafts. Does Napa carry them or orileys....or are they shitty compared to what polaris puts in. JW

3.) While your reading this, is there anybody that has taken the front gear box (differential) out to replace seals!? how hard and i was told you have to take it out strait out the front.

If you have comments, just write what ya know or have hear! thanks!

I have put a UNI air filter on every bike I've owned as soon as I got it. Never had any dust in the intake or carb. I use the uni aerosol oil and aerosol cleaner. works great. I suggest looking at UNI's website to get model number. Amazon or ebay has been cheapest for filter for me in the past (search by filter model number). I used to order from rocky mountain atv, but there model selector didn't seem to be working right in the past so i would double check the mfg part number if you order from them.

I don't have any experience on your other questions.

1.) I currently have a K&N filter with no issues.

2.) I do not know about the U- joints as i replaced my entire rear prop shaft with a sealed gorrilla shaft.

3.) There is nothing to the front differential I have rebuilt mine twice and replaced the seals twice. You just take the roll pin out of the front prop shaft, slide it off the diff., unbolt the diff., and take it out.

Discount Fleet Supply...#24245, under $12. They sell oil filters pretty cheaply too, but you gotta buy 'em by the case.
