A union is leaking fluid on my Citroen C5 steering rack. It could just be an O ring, but Citroen don’t list the part. Their solution is a new 800 pound rack. It would be cheaper and easier to sort the leak than replace the rack.

Where might I find a seal ?

bearing supplier / factors

p.s
Are you sure its not the pinon gear leaking & running onto unions?

There is a seal at the steering pinion valve but if its leaking out of the ends of rack then it’s a new rack, are you 100% it’s the rack the pipes to the rack are very common for leaking.
The main rubber to metal hydro pipes.

It could just be an O ring

or something else.
Second hand rack?

i am in SHOCK !

i just picked up a cheap used rack off ebay for my french van.

they love to develop leaks

you looked at taking it apart ? – if its anything like mine your getting skinned knuckles or employing a small child with small hands to do it for you.

flex head ratchet spanners ARE YOUR FRIEND !

dont be tempted by the pattern racks! even if they are half the price

I’m pretty certain its leaking from the rack to rack union below the pinion. I can’t see any leakage from the pinion itself.

Dingbro can do a rack for around two hundred pounds. That may have to be the solution, the car doesn’t owe me much.

I’ve got a selection of flex head ratchets.

I might just whip off the pipe and try and see why the joint is leaking first.
