My car has just had a replacement transfer box at 18 k..nsm3 wrote:Or keep it under warranty?
As an aside, I have noticed the odd 'lurch', when pulling away from a junction with significant left or right lock on. It's almost like a tiny bit of (inside rear) wheel spin which is arrested, but not due to me giving it the beans or adverse conditions, just normal driving? Anyone else get this; I assumed it was the rear drive bias, shifting power forwards, albeit not very smoothly at all? Now wondering if it may be related to these transfer boxes?
Do your cars exhibit these symptoms all the time or on occasion?Weatherald wrote: ↑Sat Feb 17, 2018 6:51 amMy car has just had a replacement transfer box at 18 k..nsm3 wrote:Or keep it under warranty?

It exhibits exactly the same characteristics as you have described from the near side rear wheel before and after the fitting of the new box.
The technician advised that there is a mod on the new box regarding a breather that was allowing water to get in, so fingers crossed. Regarding the rear wheeI, I’ve just extended the warranty for 2 years as I love the car.

It seems like the common causal factor with the transfer box failure is water ingress. I wonder if jet washing under the body is best avoided. I have never jet washed under the body for this reason.Weatherald wrote: ↑Sat Feb 17, 2018 6:51 amMy car has just had a replacement transfer box at 18 k..nsm3 wrote:Or keep it under warranty?

Also, reading other people's symptoms I'd just like to re-iterate that the clunking I heard from mine was nothing to do with having left or right lock on. Mine had problems when the wheels were pointing straight ahead - pulling away from straight junctions.
I have also read that the hesitation to engage drive when reversing may be linked to transfer box problems; I checked today and mine is still just as bad in this respect despite having a new transfer box fitted last week.
I did try to get some answers about modification of the transfer box from my dealer but they didn't give anything away. One of the technicians did say that they have not yet had a reoccurrence of the fault on any cars that have had a transfer box replacement.
@ Mark-Yorkshire - Yes the warranty extension is a difficult decision! But despite already having the transfer box replaced am 'minded' to go for a two year extension from this Sep. The bit that I would really begrudge paying is the £216 inspection fee - effectively paying for an activity that reduces their risk! I will try to get some sort of deal, even if just a free MOT!!
