I have a Monroe steering unit. According to the parts book, I don't see where there's an "O-Ring" or seal; just a cushion on both sides Plate 31F. How can I stop this leak?

As to whether the vendors might have a kit for the Monroe is another question. Posted on: 2012/2/23 23:48

The stud from the PS cylinder that is bolted to the Pitman arm?? If you need to rebuild the Monroe cylinder, I believe the usual suspects have the kit.

Is there anything special I need to know before I tackle rebuilding the cylinder? Is this the only way to stop the leak? They do have the kit. Thanks. Posted on: 2012/2/24 10:59

If that were the case you'd probably be better buying a rebuilt cylinder from Lares or perhaps one of the major Packard vendors who may stock such an item. Posted on: 2012/2/24 11:06

I got lucky and bought an NOS cylinder on ebay - just a lucky break. Posted on: 2012/2/24 19:48

They are a major rebuilder of power steering and similar units. If someone doesn't beat me to it, I'll scan one of their ads for you tomorrow. Posted on: 2012/2/29 23:17
