Hi all,
Have been told that the rear cardin joints only last 20,000klm. Anyone with any knowledge about this.

What on earth is a "cardin Joint"?

Anyway whatever it is, I haven't had to replace anything in my F250 in 120,000 Kms.

Enjoying the friendship of BOG members

Nope, nuttin' at Bushtracker on dis one...

Don't even know what "Cardin" joint is...?? Never heard of that, and I am a Fan of the Fords and a fair Mechanic on them...My own F-350, had no problems in 3 1/2 years in that department... But if you find out what that rumoured problem is I will check it out..

Sometime I have found however, that rumours on things like disadvantages or weakness in an F-250 or F-350 are started people that have not owned one... Maybe a "sour grapes" issue, Like in the Greek Fable, they can't reach it, so the "grapes must be sour"..... I might even suffer a little of that myself here at Bushtracker...

Kind Regards, stg

At first I thought a cardin joint was a cardigan knitted out of some "exotic vegetable fibre", but Mr Google led me to these illustrations at:


Takes a while to load, but hope it's helpful.

Thanks to a positive response from McTracker, I had a look, and I think I know what it is... In Australia, it is commonly called CARDINAL Joints... They are a "Double Universal Joint" and there were not any in the rear of my Ford F- 350... The most common use is because the single U-Joint runs out of application when a "Lift Kit" is put in and the "Tail Shaft" or in International Language "Drive Shaft" angles get too steep... It requires a double u-joint in the tail shaft to accommodate the steeper angle for larger Lift Kits....

That may be what they are talking about, but there were none in my own F-350 and I do not think they are in the current ones, but I could be mistaken so have a look...

They were standard as far back as the 60 Series Landcruiser on the front drive shaft due to the steeper angle... The common Engineering use now is for "Constant Velocity" double U-Joints in the Front Drive axles to allow for full time 4x4 in the steering section, where again the angles can get steep on the same power delivery on in this case axles instead of Drive Shafts... So a "Lift Kit" if extreme could possibly make them necessary on the drive shaft for increased angle, and then that warning of only a 20,000 km life could be true, unlikely, but possible. A proper "Cardinal" joint years ago went hundreds of thousands of kms, if you kept the grease up to it...

Hope to have been a help..

Somebody wanted to know what to look for...
All tail shafts (Drive Shafts) have a Universal Joint on each end to allow for movement of the suspension going up and down... They usually have a slip joint as well... Cardinal Joint, is a drive shaft that has 3, two of them together, usually on the Transfer case (gearbox) side of things, and one on the other end... They are a pain to grease properly, and most have a shortened life just because of their nature and the fact that they don't get enough grease... Anyway, when the angles get too steep and get outside the maximum engineering angles of the single u-joint on one end, that is when Cardinal Joints come into play...

I must admit, I don't recall them called Cardin Joints, but then again I have been in Oz for most of 20 years, and here I have heard them commonly as cardinAL joints...

I could be wrong, done a lot of tail shaft upgrades for custom 4x4's I have built, if I am wrong, somebody please correct me...

But that is my experience and best guess on the matter: Someone is talking about major tailshaft upgrades due to major "Lift Kits" installation.
