I'm replacing the rubber bushings on the Panhard rod on my car, and have a question about the metal sleeve bushes that fit over the threaded rod ends. One of them came off in my hand (it is pretty worn) while the other is solidly affixed. The inside diameter of the new sleeves appear to be just a little too small to slide over the threaded ends. It makes me wonder if they are intended to be an interference fit and need to be heated to expand them and then installed.

Can anyone provide guidance on this?

Thanks.

 

The sleeve it there to prevent damage to the Panhard rod and threaded end where they bolt through the chassis/axle.

I have just taken mine apart, one was badly worn and rusted to the Panhard rod, so I had to cut it off, the new sleeves were part of a Polybush set, and slipped on easily.

There would be no reason for them to be an interference fit, as there is a likelyhood that damage would be caused to the threads, if you can measure the internal diameter, I will measure the ones I have and let you know.

 

These also came with a polyurethane bushing set. The box they came in is clearly labeled as being for a Mk2 Jaguar. I did a quick measurement of the threaded rod end O.D. (0.5") and I.D. of the sleeves and the sleeves are smaller. I'm not near he garage at the moment and don't have the exact measurement.

I'll be interested to hear what your inner and outer measurements are.

Thanks.

 

The OD of the panhard rod is .496" and the ID of the sleeve I have is .501"

The Polybush part no for the bushes is 31AA.

 

I measured the ID of my sleeves at 0.496, and the OD of the threaded rod at 0.5" so its no wonder that they don't fit. They came with a Prothane bushing set with a PN of 11-48020 on the box.

Grainger sells a machine bushing that's 0.5 ID / 0.625 OD and just 1/16" shorter than the sleeves that came with the kit. I'm going to try those.

Thanks.

 

On the Prothane site the sleeves should be .63 OD and .5" ID, so you could go back to them if the sleeves are machined incorrectly

 

I spoke with a tech guy at Protane today, and he was nice enough, but not real helpful. According to his records they've sold maybe nine sets of these in the past 10 years, and he had never personally seen one.

The specs in his book say the ID is 0.496", which explains why the sleeves don't fit a 0.5 thread. It was suggested that I could easily drill them out.

Instead, I bought the sleeve bearings from Grainger. They apprear to fit perfectly, and should get the job done. I'll follow up if that doesn't prove to be the case.

Appreciate the info and suggestions provided by the list.

 

This is the spec on their site in the link below if you click on "in the box"

http://www.prothanesuspensionparts.com/1148020

2 of Metal Sleeves - 60740 (5/8 X .065 X 1.185 inches)

If you do the maths, 5/8 = .63 - .13 = .5

So they are def miss selling them if they say they are .496"
