Outer Limits 4x4 Board

I was talking to my mate yesterday and he said that the patrol 5th gear is not suitable for towing while the landcruiser 5th gear can due to its postion in the box.Is this correct? I thought there was only a weakness in the early GU 4.2td gear boxes. I am just curiouse as i am going up north to Shark Bay in WA, and i will be towing a boat.

cheers

I have heard the same but only in the 3lt's but not in the 4.2's but I could be wrong.

3lts are a problem, as for the crusiers they have a lot of problem, 75series at least not sure if they have fixed the problem in the 78series

never had any problems with my old 4.2 ute (GU) used to tow cars a bit and trialers full of pumps all around NSW, always used 5th gear

Numerous of the early GU box's had 5th gear issues.

I wouldnt think positioning in the box would make a difference, since the issue was with a shaft, nothing to do with position

meh, mine was a 99 model, turbo deisel, hiflow turbo and front mount intercooler, I have heard about 5th gear issues, but have only ever known one that went bang and it was a 3ltr

no dought, but it doesnt mean there is a big problem, or 5th cant be used for towing, it just means that is a chance of a manafacturing fault in the shaft or something like that.

My oldies GU 4.2ltr turbo 5th gear went bang on the way to Sydney. Theres a slight fault in some of the boxes with the positioning of the gear on the shaft and it basically strips the teeth off the shaft when it goes. They fit an upgraded shaft and kit to fix the issue. It can still be driven in all other gears to get i home if need be, my folks were about 400k's from Sydney when it happened and drove the rest in fourth. I wouldn't recommend it, but sometime you need to just get it somewhere.

Looks like i should not worry then. I have a 94 Gq coil cab and have not heard of major problems with the GQ boxes. I am only towing a tinny any way, which weighs 600Kg. Thnaks for the replies guys

You've got no worries with a gq mate, mines done heaps of towing over it's 495,000k life and it's never had a prob and trust me I've flogged it while towing!

How much simple misinformation can you get?


To start all 3L and 4.2L TD share the same Gearbox in the GU. Second there was a faulty shaft issue where the fifth cog would sit and basically it would strip off the shaft. Series II on should all be resolved.

Last Nissan fixed mine out of warranty and asked no questions, its a known fault. It is recommended that you tow in 4th. Mine went and it had towed next to nothing in its life.

Anyway the dealer I took mine too in Perth had done at least a dozen shafts on both 4.2 and 3.0L, mine was the 3rd that month. Takes about a two days in the shop to sort out.

This is a mate of mine and can confirm all details in this post ...
