Steering uj's. Pressed, froged or CBS chrome?
Evening all
I am just putting together the steering on my Thruxton.
I have some standard pressed UJ's and can't say I like them very much.
Is it worth going for the forged ones or even the chrome ones from CBS?

Very nice but not exactly locost!
Cheers

We used pressed and forged for Ford & Jaguar and all forged items for Toyota when I worked at the steering column plant.
I would go with either the pressed or forged ones whichever is the cheapest.
I tested a rolled pressed item on a torsional tester and it destroyed the uj at around 350 tons.. so no need to worry.

heard reports that some of the pressed ones are a little "aftermarket" ie dubious. However, I have just fitted a forged one (onto my
triumph) and that seemed nicely made, if a tad chunky. Little difference in price, but if you pressed ones are OK, fit on the splines easilt etc, I
would use them.
One last point, I read elsewhere that "rally design" had a disclaimer in their price list about there pressed uj's, may be worth
finding?

All the UJ's on the Mondeo, S type Jag and older 'Ford' models used pressed items, onlt part that was dropped forged was the bottom
drop link.
And, the current AM DB9 uses pressed items as well seeing as they use the same column as the Mk2 Mondeo...

Steering UJs always fail by the universal joint needle rollers seizing up.
