PS idler arm
Hi all,
I have new bushings for my PS idler arm but the bushings that I took off had these cups. Do I need to keep them with the new bushings? They were the original bushings. Thanks, Mike

Re: PS idler arm
Below is an ILL of OEM install (complete service kit). Those washers look like they are from a 3C590 kit (steering cyl bushing kit).
Did you just buy the bushings or a complete service kit?

Re: PS idler arm
I just bought the bushings. I will look at the kit and see if I can get the washers as well.
Thanks, Mike

Re: PS idler arm
What you have may not be OEM but aftermarket.
There were so many vendors (and quality) over the years it would be hard to ID. Let us know what you find.

Re: PS idler arm
I think it is original do to the rust/ dirt on it. But then again it could have been replaced 50 years ago at some point. Either way I will put it back together with the washers.

Re: PS idler arm
Ok, so I think I have this thing mocked up correctly-I got lucky in that the bushings just dropped right onto it. I also noticed that the bushings were slightly off center with the inner sleeve, will that be a problem?

Re: PS idler arm
There is something about the arm itself and the take-off bushings that doesn't seem quite right.
Below are other ILL's showing ASSY and DETAIL. The washers have to be flat as to not interfere with inner/outer bushing sleeve movement. If you go ahead, make sure the concave washer does not interfere with the bushing(s) (turn upside down) and don't fully torque to spec until steering wheel is centered and toe can be set correctly.

Re: PS idler arm
The 1956 model year was the first time they switched to the encased rubber bushings on the idler arms.
The '54/55 cars with power steering had a very complex system incorporating a set of standoff/inserts at top and bottom of the steering arm or idler arm bracket. There was an accompanying large round roller bearing and flat-washers that sat on the standoff at each end. There was no need for a press. The standoffs were machined to fit snugly in the bore of the steering arm and idler arm bracket. Each roller bearing had a grease fitting. The problem with this arrangement was that no one ever greased the roller bearings, they dried out and started to cause hard steering. However, the design (if it had been properly maintained) was superior to the later encased rubber bushings. Once upon a time, Timken made replacement roller bearings, but the pattern was dropped when they started stamping in china, and no other bearing companies produce replacements for that pattern today. I had a complete original '57 PS setup which only had the metal encased rubber bushings with large flat-washer and castle-nut on the end. Flat-washers were only about 1/16" thick. |

Re: PS idler arm
A few years ago, you could buy the whole kit including idler arm, bushings, washers and castle-nuts. Now, some vendors are only selling the bushings.
If you had an earlier idler arm replacement from a kit, you may notice that the shaft portion is way smaller than the original, but they cast-in a couple of "gussets" at the base of the shaft to keep the shaft centered. Those gussets can wear-down and cause too much vertical slop in the idler arm movement. So if you can only get bushings now, it may not help if you had one of those aftermarket idler arms. |

Re: PS idler arm
That second photo is a roller bearing kit for '54/55 (and would fit the '56 idler arm), but I don't think the old style was available at the factory anymore.
The original print of the '56 Ford Car shop manual shows metal encased rubber bushings for the PS idler arm. (that could mean that the early '56 cars might have had some of the '55 idler arm kits, but that the rubber bushings shown in the shop manual were the factory authorized replacement). What bothers me is that his '57 idler arm has large recessed washers on the shaft ends that have no value at all with the use of rubber bushings. I think that idler arm came off a different car. Mercury or Edsel maybe? |

Re: PS idler arm
Here is the bracket and large bushing that I knocked out. No bearings in it-just lots of rubber. I do have a relatively early early car-I think. It is numbered 156915 from Norfolk. From what I have read you drop the ‘1’ so that would mean it is #56915.

Re: PS idler arm
Thanks K,
This car is so banged up anything is possible. IT may have been rebuilt/replaced decades ago. But will start looking. Mike

Re: PS idler arm
After seeing your avatar photo, I was under the assumption it was a cherry piece. The parts are out there if you know where to look. I wouldn't trust anything new as to quality. Once you have the kit you can use those bushings for rebuild in the future.

Re: PS idler arm
I see that you have the idle-arm bracket and the other half of the bushing that came out of it laying on the garage floor (picture upside down).
Can't say as I have ever seen an assembly like that. I think it would be a big help if you had a '57 Ford car shop manual to see what the factory showed in their illustrations and try to order those parts if available. I just looked at the latest Mac's catalog and they are not offering the complete kit for '57 Ford with PS. They do offer the metal encased bushings (MA-3358-A & MA-3356-B), but I am sure those won't work with the idler arm you have. |

Re: PS idler arm
K=thanks for the info on the build date, that may explain the June 14 1957 build date instead of earlier in the model year.
Dave, I was looking at my manual and their pics don't show anything really. just bad pics of the system. I did see some rubber bushings like mine in a catalogue but they are for a non-power steering bracket. So it is possible that someone rebuilt it with non PS bushings at some point in time. Those are the bushings that I bought for this application as they are for the PS idler arm according to Concourse. Mike

Re: PS idler arm
If you type in ' B4A 3352-A ' in your SEARCH ENGINE, you may find a NOS on EvilBay.
There is an aftermarket still offered - https://www.jamcosuspension.com/prod...ering-ia5460ps It says USA but I have no idea of quality.

Re: PS idler arm
Update. I got the PS components rebuilt and installed. Only to find out there are two issues. Neither of which were really my fault. First I apparently had the bushing installed backwards with the long one in the center link and the short in the bracket. They should be reversed-according to a spare 57 PS set up. I also noticed the idler arm is different from the spare to mine. So my thinking is that they had to replace the idler bushings at one point and couldn’t get a PS set and used a manual set up.

One of the two is correct, I just need to figure out which one.

Re: PS idler arm
The take-off shown below is not correct. It must be an outside vendor service replacement. You would need the original busing set to make it operable -

Re: PS idler arm
I have installed, I just have them in backwards. So I will send it back to the shop to get them reversed and then reinstall.

Re: PS idler arm
Ok, all of the PS components are temp installed now and appear to work as advertised. Now how do I tell which side which long tie rod goes to?

Re: PS idler arm
The info and illustrations on page 4-4 of the '57 shop manual may be helpful.
Rotate the steering box or steering wheel back & forth a few times until you can determine when the movement of the steering box & pitman arm is centered, the middle spoke of the steering wheel should be pointing straight down. Point the tires & wheels straight ahead and the tie-rod placement may become evident. . Last edited by dmsfrr; 10-08-2021 at 08:08 PM. |
