GU 3.0 Thrust Bearing

Ken,, A noisy thrust bearing will not affect your clutch as it only works when the clutch pedal is operated and is just a thrust bearing that contacts the pressure plate diaphragm that disengages the clutch. However if it is real bad and starting to seize it can cause wear on the diaphragm over a period of time. If you have been driving in water it may have got water in the bearing causing the problem.

Hi KenA, Any noise from a thrust bearing means only one thing " IT IS SHAGGED". Throwout bearings DON"T have "FUNCTIONAL NOISE". If the dealer won't accept it as warranty contact Nissan Head Office Yourself, Nissan Dealers are all too good at shirking responsability on warranty claims. I Know I am right here as I have had 25 years experience as a Qualified Diesel Fitter. Rip it up them, don't be stood over to save them a few bucks, they'er good at taking it off you when you buy the thing in the first place. 50,000 is pathetic life for a throw out bearing.

Thankyou Nav, RosscoH and Andrew W. I shall be very interested to hear of Nissan's reply on ? Monday. Certainly I shall pursue the matter to its fullest and have had dealings before with the customer support manager at the Nissan Dandenong office. Thankyou again for your quick replies.

Hi

I have a 2003 GU 3.0 litre Patrol, 34,000 Kms (out of warrany) I have had noisy spigot bushes for about six months now (only when cold) Also I have a knocking noise at idle sometimes, but if you increase the revs, it will go away. I went to Nissan about this (when it was still under warrany) and they said that they never heard about this before (the knock) yeah right! Anyway, I will replace the clutch and spigot bushes with after market,Exedy, parts. I will also replace the flywheel with a solid type one at the same time,as this is the cause of the knock at idle. the clutch kit and solid flywheel, from Exedy is about $1250 trade price (for anybody with the same problems as me).I know I should have pushed for Nissan to do this while it was still under warrany, but at least if you do it yourself you know it was done, and it was done correctly! and you wont be without a car for,god knows how long!

Hi HL. The deepest water I went through was about 17 months age (the Mitchell River at Angusvale) but the water was no higher than the top of the tyres. We had stopped for about forty minutes prior, to allow things to cool down before doing the water crossing as is advised. I would have thought though that the built in idea of a high ground clearance vehicle like a Patrol would be to be able to go through water etc without ingress problems and I'm sure many other GU's have been through water deeper than the crossing I did. However, I shall word and verbalise my enquiry to Nissan politely.
Thanks,
Ken

Mine did the same thing at 30,000km and was replaced without question under warranty. It's a Landie not a Nissan but that shouldn't make any difference.
