Cv joint failure

[Problemchild_87]

My brother owns a VY SS ute he has just had the second tail shaft CV joint fail within the last couple of months

the ute is lowered to the legal limits wondering if this is causing the extra strain on the joint and is there an aftermarket CV designed compensate for the ute being lowered

Thanks

I have heard that a 4 point camber/toe kit will put extra strain on these drive line components, so if he has one, then a switch two a 2 point kit could help, although failure this quickly surely could not be completely due to a camber kit.

When you say 'legal limits' how low are we talking?
Basically, the lower you go, the less 'give' in the spring and that 'give' is transferred to strain on these driveline components.

Lowering the car pushes the CV joint inwards and can cause binding during suspension travel.
This can also damage the diff if it bottoms out inside the CV Joints.
Also fitting second hand shafts from a standard height car puts them into a different working area inside the joint where the balls have not been working before hence cause stress from different wear patterns.

Welcome to the joys of lowering a car too much.

I spose he can think himself lucky his diff has not let go yet, but if the shafts are bottoming out its only a matter of time before his diff is rooted as well.

Fitting a camber kit can stand the tyres up a bit more and lengthen the shafts in their working area but thats only a bandaid fix realy, do its have much camber on the rear end?

Just to confirm what you are saying... What has failed the "Tail shaft" OR... rear "CV joint" as they are two different things???

The "Tail Shaft" is the thing that comes off the bearbox to the diff while the CV joints go from the center diff to the rear wheel hubs/disks.

im no expert iv been told its the tailshaft CV joint, im sure he ment the cv joint

[Aussiecv8]

I think he is talking about universal joints, not CV's.

def sounds like uni joints one each end of the tailshaft

[Problemchild_87]

Starts with a ticking sound then bang no drive to the wheels

The correct terminolgy for the one on the tail shaft is: Uni Joint and/or donut coupling and there are at least two in our modern vehicles, with I think from the VN onwards ther are 3.... a camber kit will do nothing for this.


The correct terminology for the one between the diff and the rear disk/hubs is: Rear CV joint/Rear stub axels... and a camber kit will help a little, tell him to stop doing 9000rpm burnouts and driving like a twat as this is what fcuks up these.

we've all tried telling him to stop driving like a fwit (converted FORD driver) anyway he got it to a machanic today there going to try to source shortened tailshafts for it next week
