WARNING - Not all CV drive shafts are compatable with Xtrail
Hi all,
Had the front CV drive shafts replaced with new and started having problems with the 4WD electronics. Symptoms were LOCK light came on after driving for a couple of minutes in Auto Mode, then 4WD light started flashing another couple of minutes after that.
Service manual says ...
"LOCK light will come on in Auto Mode if sensed wheel speeds between front and rear are different. This is normal"
"4WD light will flash to indicate possible overheating of rear transfer due to difference in speed between front and rear wheels."
So, after much looking and comparing, I found that the teeth on the ABS sensor ring of the "compatable aftermarket" CV drive shaft were wider than on the genuine part and the gaps between teeth were smaller. From this I can assume that the sensors are misreading pulses and the electronics are getting fooled about true front wheel speed.
Everything is fine in 2WD because the pulses are only used for ABS operation and the number of pulses for each rotation are not relevant.
Just a kind word of warning.

Re: WARNING - Not all CV drive shafts are compatable with Xtrail
This particular one is from a CV joint and driveshaft supplier and reconditioner.
His parts manual says it is compatible and he has sold more than 20 to independant mechanics but this is the first Xtrail he has fitted some to himself.
He understands the problem and is trying to find out more information.
Worst case is that he has to recondition my old ones and refit them.
Just not looking forward to the hassle over costs. Should be no problem about parts return since the driveshafts are not fit for purpose, but the double labour charge for fitting and then refitting will be something I am sure he will argue and I shouldn't have to pay either. We will see on Monday when he gets another chance to sort out the problem.

Re: WARNING - Not all CV drive shafts are compatable with Xtrail
What's the difference in price buying them new and genuine from a dealer compared to what you have experienced now with incompatibility and does it worth the hassle?

Re: WARNING - Not all CV drive shafts are compatable with Xtrail
$220 each for a new complete driveshaft with 40,000km warranty.
$150 each for a reconditioned complete driveshaft with 20,000km warranty.
Nissan want $110 just for the CV boot and no guarantee on what your old CV joint is like after running dry without grease for an unknown time. Even the dealer said they would have the original driveshafts reconditioned rather than getting new genuine parts due to cost.
I initially went for the new driveshafts, but if a compatible unit can not be found then I will have my old driveshafts reconditioned. This will work since they will have the original ABS sensor rings.
If I find out there is a 100% compatible new unit I will post the part number and supplier here for everyone.

Re: WARNING - Not all CV drive shafts are compatable with Xtrail
Yeah, the teeth gullets are definetly wider on the original shaft.
It also appears that the input shaft is longer on the original where the spline stops near the CV.
The spline on the new one runs further towards the CV.

Re: WARNING - Not all CV drive shafts are compatable with Xtrail
Hi Rich,
Yes it was a difference between front and back wheel speeds that was the problem.

Sometime after my short sway-bar arms were replaced (both ends popped out of sockets) I've noticed over the last several months blobs of grease around the wheel arch and nearby suspension components. The outer drive-shaft boot is dry, however the inner one (nearest the gearbox) is covered in grease, particularly around the inner-most clamp (which holds the boot in place). I haven't cleaned them yet to try and find any holes, and I'm probably jumping the gun by blaming the workshop that repaired the sway bar for damaging the boots, and as I've just done the 90,000km oil change so it's probably about time they busted anyway. The lift could've also been a contributing factor in the leaking grease, even though we have barely been offroad since doing the lift (only once, which was the roughest we've ever done!).
No knocking, so the drive-shaft/CV joints are probably still OK, but is it worth just changing the boots, or change the whole drive-shaft (assuming that's what's done when you get reco'd CV joints).
Kev, care to elaborate?
Initially I was going to only replace the boots and could not decide as I mentioned earlier between $110 for a boot or $150/$220 for a complete driveshaft with warranty. Labour would have been about the same and not knowing how long the CV had run dry was a factor to consider.
I eventually decided on the complete drive shaft replacement when I started getting a shudder from the front because of the worn CV joints running without grease.
