Patrol Clutch.

I had a similar problem with backing my trailer a couple of years ago. I slipped the clutch , and you could smell it. It shuddered for a few days and settled. still going ok! My 03 4.2 Tdi has just clicked over 350,000ks with the original clutch. My 99 4.2 td clutch did 350,000ks and finally died towing a triple horse float... I've had both Patrols from new so i know they are original. I see a lot of guys still getting low ks from these so called heavier clutches, maybe they abuse them but I reckon the Nissan is as good as anything else. Exedy claim they have a 25 % more clamp but who knows. Nissan clutch is about $650 i'm told, but I haven't actually priced one myself. We want to start doing some more desert trips so I guess I will be forced to change my clutch for peace of mind but i'm still reluctant while it feels normal. I guess its up to you what you do, its your call. Michael

I would always use a genuine full clutch kit and replace rear main seal.

My Nissan at 60000 kilometres required a new clutch (pretty typical for OEM clutches these days). I replace it with a 4Terrain Semi Button clutch which has now done over 320,000 k. I would highly recommend the 4 Terrain.

Like guya above I would stay with a standard clutch - you don't actually want more clamping power you want fine control.

Mine started to tailor off around 200k , partly caused by slave cylinder not acting fast enough as it was a bit gunky - got a changeover and it helped but at 250k facing more desert drives I just replaced it.

It can be done at home but I don't reccomend this as its a heavy box.

I had the same problem with mine, 05' TD4.2, normal driving it was ok but when towing the camper would get the shudder up. I also do not like the feel of the Patrol clutch, too soft and vague, changed it out for a Safari Tuff, much better in my opinion, little heavier but much better feel.
The old clutch plate still had plenty of wear left in it but was very glazed, which is probably what was causing the shudder.
I have also fitted a set of Marks Adaptors 43% low range reduction gears, which has reduced the need for any clutch slipping when towing the camper in low range offroad situations.
