Steering linkage with UJ's

[mikeyp247]

Wondering if anyone can help.

I'm after a 2 or 3 part steering linkage with UJ's in it, something like this:




BUT


One of the openings where the splines fit needs to be 3/4" (as that is the size of the stem unit I need to fit it in to) but the other will have a steering wheel welding on to it so could be any size really.

The 'centre' bar needs to be as short as possible.

Any ideas guys?

Don't weld a steering shaft. They should never be welded.

Cheers for the comment. I know - but this isn't for a car, so it's OK. I really should have been more clear when I posted.

I am building this - but it is now not going to be a soapbox. It's going to end up as a Toylander type thind, but I need to change the angle of steering input and UJs is the way forward.

Please forgive the crudeness of this pic, but I'm trying to get to something like this (where the red and green assembly is the UJ/steering rack):



(shortly after posting this comment, I shall update the thread with the new plan too)

Does that help to make me sound any less daft?

The welding would just be to weld a steering wheel on to a short shaft to insert in to the UJ on the smaller green circle.

Which part of the Internet did you read that on?

its a bit of a contentious point, as its potentially an MOT fail.


2.2.C.E.
reason for rejection-
"inappropriate structural modification or
repair by welding to a steering linkage
component, or signs of excessive heat
having been applied."

its that word 'inappropriate', which is down to tester discretion. ive seen some right bloody lash ups of butt welded together solid bar pass with one tester, whereas another failed a proper sleeved, pressed, drilled and rosette welded column on another car.

Thank you all for your comments and that's all great and stuff guys, but this ISN'T going on a car.

So if you have any idea where I could find a 2 or 3 piece steering UJ section that has at least one 3/4" section of rod on one end that would be really helpful.

yeah i know, jut answering slaters point.

try corsa C. they have a telescoping twin uj, they're *about* 3/4" as the actual shaft is that size, you could drill em out/slim down the shaft a little/weld it all together or whatever. i have to modify them for doing corsa EPAS setups, but i don't actually use the other end that doesnt go onto the epas unit so doing know what size it is. they're cheap too, about a tenner of ebay.

Ah right, OK.

Cheers for that info, am I right in that you mean this piece?

Looks promising. Does the telescoping shaft come apart easily? I guess this is the bit I would weld together.

Inappropriate is the key word as you say if done properly wouldn't be noticed by a tester. if in doubt P&A.

yep they jsut knock apart. the inner diameter of the smaller part of the slider is 18mm with a flat on each side, i know that as its the bit i use.

Cheers Dez, appreciate it - will give one a try.

Thanks Dez, and sorry to the OP for hijacking the thread.
I base my knowledge off the Australian rules, which I'm sure used to say no welding allowed at all on steering and suspension, however I just checked and there is a new version from November 2015.
Now, we are allowed to weld steering and suspension, but each modified car has to have an engineering certificate with detailed drawings of each component, and each weld has to be hardness tested and X-rayed by a NATA-certified laboratory.
