Hi folks,
I have this 1994 Uno 1100 with a new problem. While driving it will all of a sudden make the most horrible metal and knuckle busting noise possible coming from the front. When this happens while going forward or backwards it sounds like the wheels are breaking off the car. (The left hand side one). Also it feels like I am bumping over large rocks. So the wheel is turning unevenly – a LOT!
I have found through inspection that I am able to literally push the left shaft back in/towards the diff by about 6mm. In other words at that stage there is a 6mm horizontal play on the drive shaft. Once I have done this, I am able to drive for quite a bit before it pops out again. Only about 6mm. This got me thinking. Where on earth is this play coming from.
IMPORTANT OBSERVATION: Also, the moment I push it in, I am NOT able to wiggle it back and forth any further, in other words the play is missing and everything is normal again.
The hub nut is as tight as hell and definitely not loose. If it was a weight problem or track arm problem, then surely when the weight is changed, it would self-correct. Also I’m almost sure that moving the tripod 6mm out from its default position will not pull it out far enough to disengage from the diff.
My conclusion and this is where you guys come in, is that the CV joint is damaged in such a way that the shaft actually comes loose inside it or pushes a little bit further into it than it should, causing all the horrible sound and bumpiness. It must be pushing in about 6mm it seems which is where the temporary free play comes from. Then I simply push the shaft towards the diff (pulling out of the CV) and all is good for a while. Can anybody please confirm if this is at all possible and if the problem is not somewhere else perhaps.
The part which drew my conclusions towards a buggered CV is the fact that I am able to move the drive shaft so easily while all four wheels are solid on the ground. I have replaced the tripods a while back and checked them yesterday, they are just fine, no sign of damage inside the diff (looking in from outside) either.
Please if someone knowledgeable can just check my conclusions and understanding it would really help a lot.
We are leaving town soon and hitting the long road. Got retrenched – AGAIN! So we need to get the old lady back to a reliable state. We don’t have a lot of money therefore cannot afford to run the regular trial-and-error approach the mechanics have over here in order to sap the last pennies out of people.
Please help!
