My 4WD Granvia has gradually developed a knocking noise underneath. It sounds quite heavy and when driving I think it comes from under my feet - but passengers hear it elswhere. It only happens on taking up drive - setting off uphill or a quick pull out of a junction. It is two or three knocks - like a gear slipping or a loose mounting causing a part to bounce under initial torque loading.
The gear box mounting was obviously knackered and has been replaced and so has the offside top ball joint.
The garage think it may be in the drivetrain. They have checked the drive flanges in each front hub - some slight play but not slipping. They have checked the oil in all the casings - all clean with no swarf.
The front propshaft is quite new, having been replaced by Toyota under the safety recall. (If yours hasn't been done take it to a main dealer and they will replace it for free!)
If anyone has any ideas or previous experience of this knocking noise and any assoiated fault - please let me know - it is driving me and now the garage nuts!
Internal part from Toyota - £900+, whole box from BBC Spares - £225 plus VAT. So BBC win again. With luck I might be back on the road on Friday!
The front propshaft was replaced a year or two ago so I don't think I can blame the main dealer.
The front propshaft on the four wheel drive version had a problem with the type of grease used and so suffered early wear to the universal joints.
Having found out about it through the old forum I hassled my local Toyota dealer and Toyota UK until they agreed to replace the shaft under warranty. They said mine was the first they did, but now they have the info on their system they will do any.
It is a safety recall so there is no charge, but as the UK was not the intended market for these vehicles you have to contact Toyota - they will not chase you to offer the work.
Our granvia has also developed this loud knocking noise!
I've replaced one of the front drive shafts as the splines on the flange had some play in them but the noise is still there; before we go ahead and replace the other drive shafts I wondered if the transfer box was the problem.
How did you get on with yours? Was it the transfer box in the end?
Have contacted Toyota UK about getting the front propshaft replaced too so thanks for that info. I also found out that the cooling system also has a recall as one of the caps is not as heat tolerant as it should be along with a few other recalls for the Granvia (not relevant to our model) on the following link: http://www.dogandlemon.com/safety/recalls/jp/toyota/granvia
Many thanks in advance for any help/advice you could give.
Only option now is to find a mechanic who will do the work once we've sourced the prop shaft and the transfer box (hopefully BBC will have them) and hope that this will fix the knocking noise.
Don't you just love owning an import?!
