    zf vs koyo steering rack?

    Guest-only advertisement. Register or Log In now!
    My steering rack has been leaking. I put in an order for a koyo rack from discountsteering. Had it shipped all the way from the west coast to the east coast, to find that on the rack it says zf branded on the rack near the top mounting hole. Ive read they are not interchangeable. My question is, has anyone used a zf when your rack was koyo?

    nvm may have found my answer.

    Pretty sure this was a 4cyl vs 6cyl difference from the factory. I think the 1.8T's got the Koyo's. Anyhow, I don't think there will be any problems. The steering may have a slightly different feel. I think the V6 rack was dampened a bit more, or some such. Don't quote me on compatibility, as I haven't done the interchange myself.

    Thanks for the reply. I'll be putting it in tomorrow, should be alright. I believe just the inner tie rods are different. As long as the new rack came complete with inners I should be golden.

    Hey viet,

    I'm about to do the same thing as you. Did you get this installed? Were there any problems with the rack?

    as long as it bolts in I wouldn't worry about it. I know mine used to have an internally dampened rack and now it's got the externally dampened but I didn't install the dampener. Gave it a more responsive feel.

    They're interchangeable, I had a Koyo rack put in place of my ZF rack. However you may get boned on the core charge which will set you back. Also, the tie rods may be different, I'm not 100% sure.

    Yeah the rack is in. Only problem I had was getting that damn 22 banjo bolt on. Took me over and hour trying to start it. I had to replace my outer tie rods even though the ones on my old rack were meyle hds I put in less than 6 months ago. In the end the job wasn't too bad took me about an hour to unbolt and remove an about 4 hours to install.

    Good to know. My outer tie rods are almost brand new, I just did my control arms last fall. Looks like I'll be ordering a new rack today.
