    I have Haldex slack adjusters on my truck. Haldex 22021 to be exact. I cant find any of these online. When I go on eBay I read that the Haldex 22021 is an OEM replacement for 409220019( IDK what brand)

    Is there a way to find a replacement I don't want to go to dealer. I have a few weeks before I replace them all. Im definitely not going to KW to buy them. Id like to have them waiting on me when I get home.

    Yea I use them to....didnt have it... come to find out the 409220019 number is haldex also. So now im thinking the correct part number for the haldex 22021(this is what's on the slack adjuster) is 40022021..... or its missing some numbers that aren't on the slack adjuster.

    I also have the haldex slack adjusters. As far as I know all of their actual part numbers begin with a 400 or a 40 number.

    If you have genuine haldex slack adjusters clean them up really well because those numbers are on there. If you can't find it on one clean the other ones off because those numbers are there. I believe the number 40020221 is correct.

    If you have a transaxle location near you that's where I bought mine and they had the right price for them. If not maybe they can even ship them to you.

    I am certain they can tell you the right part numbers and I think they can even search by VIN. I know at least for my Freightliner they could search by VIN. And I think they can also search by your axle if needed.

    When you search haldex 20221 you get this link: 40020221 - S-ABA Service Kit - Haldex product

    If you go to that link that will tell you the number of splines and it will show you the size of the slack adjuster. If you get under your truck and you count the number of splines and you actually measure the length of the slack adjuster you can double-check that's the right number.

    And of course you can also call haldex and ask them if there's any part number like you have but I'm 99.99% certain they will give you a 400 number for that which I believe is what you have 40020221.

    Also as far as I know as long as it is the s- aba type, the only differences between them are the number of splines and the length of the slack adjuster itself and if it is angled or straight.

    Well I would call haldex directly. I've called them before for other things and they will get on the phone and answer your question. They can probably even tell you where a local distributor is that you can buy them.

    But myself I still believe that the right number is what you have with a 400 in front of it. And like I said if you get under the truck and you count the number of splines and the length of the slack adjuster that should tell you if it's the right one.

    Let us know what happens.
