Steering rack bushing/bearing

[Sebscst]

I need to order a new steering rack bushing/bearing. Im talking about the one at the end of the shaft in the smugglers box. I have done some searches and see where others have said the oem one is crap. Others have bought the bushing and separate bearings and have made their own. Just trying to get some input. The post were about 7 years old and dont know if there's anything new or if someone is providing a better alternative. Thanks

Thanks Dmitry but thats not the one im talking about. Its the bushing with the internal needle bearings.

I replaced mine with a exact fit from a bearing supplier last year. I'll try and find the dealer and part #. The one in the rubber/plastic collar that gets clamped down right?

The one in the "needle bearing steering shaft" link is the one I did but I can't find the dimensions and where I got it from. It's #23 in the PET catalog, part # 911 347 041 00

Yep thats it. I have found some online that look like they are just the rubber bushing but they say nothing about a bearing inside. My car has neither of these parts so i need both.

Found this

You should find the information in the following thread:

Steering Shaft Bearing

I was able to go to a local bearing supplier with the bearing part information and find the bearing and seals and rebuild my bearing that was totally rusted up. This cost me around $30NZ. If I can find the parts here in NZ then you shouldn't have any issues where you are.

Best of luck,

Search HK1712 -That's the one. You'll also need two seals of some sort who's ID matches the OD of shaft and seals OD "matches" the ID of the rubber bushing. I'd say get the bushing and bearing first and then work backwards to find the right seals to fit in the bushing.

There are two distinctly different parts.

Early cars had a rubber sleeve (similar to the yellow Powerflex sleeve) and this fitted over a bearing.

The rubber housing is still available 901.347.223.03 but the price has recently increased dramatically.

The steering shaft bearing is the HK1712 needle roller but fitted into a steel block with felt washers to hold oil and a pair of seals.

The HK1712 bearings is of no help if you don't have this housing.

The 'bearing unit' is 901.347.241.01 and is NLA.

These two parts have been replaced by 911.347.029.01 and this is a rubber housing with a bonded-in needle roller bearing.

I don't think that the bearing is removable without wrecking the complete unit and they cost around $100 each

I have a few rubber housings in black and we make a different version of the bearing unit.

Every steering bearing we strip has 'jammed' needle rollers which causes skidding on the shaft.

A needle roller is just not quite the right design for this application.

They just don't seal well enough and the corrosion jams them.

Why use a bearing with a 14000 rpm capability and poor side load capacity of this job?

We make a housing fitting with an oilite bronze bush, felt washers to retain oil and R21 lip seals to keep out the crud.

The are $30 each (Rubber housing not included) and I am just about to source black Powerlex PU housing to complete the job.

Sorry about that! But I'm glad to see that you found the part from a fellow forum member!
