Steering Rack. Knocking, rebuild?

[miller]

So an annoying knock has been diagnosed as the Steering Rack. Despite the seals being done last year. If I send it to be rebuilt is there a parts kit I can buy for the rebuild? Whats the likely culprit here? Im not too familiar with steering racks! Help please....

Koyo Rack so original OEM.

Are new racks available to buy? Does the KOYO OEM part cross reference?

Im really struggling here!

Im the other side of the pond am afraid. Detroit wouldnt be close

Anyone got any tips on how to search for the Koyo Part number? Mine is half missing, id like to try and cross reference other models in case the rack is same... Really struggling now on this

I have a part number for the seal kit. Gates 348800.
I bought it through Rock Auto years ago.

Edit - realized you were RHD. Here is a link to the blown apart diagram with corresponding OE part numbers for cross referencing. The majority of stuff is no longer available, but it at least gets you into the world of finding alternative parts if needed.

On RockAuto I found Edelmann (?) seal kit EDELMANN 8658. Link is here: https://www.rockauto.com/en/moreinf...vKQo6h/HXEKBvFHsbHv8ti8sQpUJ7g0MA7NmCNXkuEa+A

I DONT know if that'll work for RHD. I don't know if it's any good. I just know it exists.

As a query, if there is play in the Rack, do those washers and seals in that kit take that play out of it? As well as fresh seals.

Nope, but there is a shoe on the back behind the pinion you need to adjust. The bottom of the pinion also runs in a roller bearing. I’ll look out the uk place i used for seal kits and post for you. If there’s play stop using it as you’ll knacker up the rack and pinion. Do you have the shop manual?

 

[miller]

No shop manual here am afraid, any link to it? As an update though, I dropped the rack into a service shop in Dublin two days ago. I got a call yesterday that they had inspected it and they can repair it. I am due to pick it up later on today, with a view to fitting it in the coming days. Ill report back then.

 

[misterfixit]

Glad you’re getting it sorted. It’s been a long day here so it’ll not be tonight. I’ll dig out the info from the shop manual and the tech info manual and share that.

If you look at my index post in the tech section you’ll see some of my shop manuals.

kind regards,

Richard

Thanks Richard, good to know there are a few experts this side of the pond!

Turned over some rocks to find the company I bought seal kits from way back when.. Here is their webpage as a screenshot:
Looks like Covid and Brexit export restrictions killed it. It was dissolved in 2021 per companies house.

 

[miller]

Brexit once again proving it was the biggest shooting your own foot incident in history!

Cheers man....

 

[misterfixit]

Indeed…

So last update on this. I had the rack totally reconditioned and refitted. The knocking has now dissapeared so all good. There is still some very very minute play in it, which is put down to wear and tear on the worm gear. But overall its made a huge difference. No more 'shakey' steering wheel that feels like its loading and unloading and no more knocking.
