Steering Shaft Wobble
Steering Shaft Wobble
(OP)
Hi All
I am having trouble with the steering shaft wobbling as it turns which is causing interference problems in near by components. This is a manual rack and pinion system. The steering shaft has 3 ujoints in it. I am aware of keeping the ujoints in phase to help the problem, but this doesn,t seem to help. Is there somthing that I am missing or some trade secret to getting the shaft not to wobble?
Any input will be greatly appreciated, or if you would like more information let me know.
Thanks and good luck!

RE: Steering Shaft Wobble
Is this a properly designed system or something you've put together as a prototype?

Thanks for the reply!
There is one bearing on the first intermediate shaft coming down from the steering column.
The current system should be considered as a prototype. We have put about 15 of these vehiles together to use for protyping and marketing purposes. It seems that every system that we put together was a little bit different. Is this possibly due to out of tolerance parts or is it typical for these systems to each have a little different personality?
RE: Steering Shaft Wobble
Perhaps you could give us some coordinates?
eg brackets on the steering column, position of each UJ, position of I/S bearing
Do you have any slip (plunge) joints in the system? If you don't the forces can be enormous.

RE: Steering Shaft Wobble
the first and second uj are at about 28 degrees and the third is at about 20. I dont have any plunge joints in the system. After thinking about what you said and the way that the system acts this may be very benficial. I will have some more time to work on it towards the end of the week or early next.
Thanks for the help and i will let you know how it goes.
