Patrol (coil) vs. Land Cruiser HD (HZJ 79)

And i guess al frames are the same within the model? Or does Nissan Australia manufacure stronger frames?

Because in case of the axles, i heard the stronger H260 was only available in australia? At least für the Y60?

Maybe it's more regular in the latest patrols here in europe, the last ones came out in 2009.

But something i wonder about: if frame&axles are better from nissan, why does toyota hold the main market share? The J80 series was quite luxuary, so i guess it#s hard to compare here, because the customer had to be willingt to pay more, but the j70 series is around the same prize, but it has been sold more often right? And as far as i know, the 7 series does have the higher gvw - why so is the patrol is stronger?

Yeah of course, but since the gvw is already a bit lower as the gvw of j7 it should be not that big of a problem. Of course we can only guess what happened to the frames, but thos cracks are severe. Maybe something like that did also happen to J8's or HD-J's as well but we did not hear of it.

GEKO-seems to have some experiences over years and he seems to know more people who got serious with many patrols, maybe he can explain.

I suspect that marketing has a lot to do with Toyotas' greater market share. They also seem to have the edge in luxury, which appeals more to the masses than off road ability. The 70 series would also have a higher gvw than a patrol because leaf springs carry more weight than coil. The coil sprung Toyotas would be a better comparison to a Y60 or 61 unless the utes are being compared.
 
Hi

Oshkosh: It would be good for this discussion if you can tell us where you're based.

Axles: Even the H233 is a lot stronger than LandCruiser's axles. It is so obvious when you have them both side by side… The Patrol big ring and the pinion are so much bigger… Even the differential itself with its satellites… teeth on Cruiser's diff are not that big at all… I opened and overhauled mine at 200'000kms when I got it (stock and withou towing package)… I was pretty shocked to see how the little teeth of the satellite was worn out… The worn would not be better on a Patrol's diff ( I don't know), but the size of the teeth would make it more acceptable.

Toyota vs Nissan: Toyota has more economical power, a better network, and a better choice of vehicles to offer. Then, when you come to compare the success of each other, in the 4x4 field, some major facts:
- Toyota always believed in the third-world market. And Toyota still has a great network of dealers and facilities all around the world. This is the first reason why UN, NGO's and associations always preferred to buy Toyotas.
- Having these organizations as clients helped Toyota to stay behind their partners and continue to support / manufacture 4x4 with african spec.
- Toyota ofently was heading the competitions in terms of luxury and engines. Exemple: the Y60 with the 4.2 or the 2.8TD only led from 1987 to 1990. Then Toyota launched the LC80, with a more modern shape and a more powerful engine. Then While Nissan launched the Y61 with a moderner shape (still with the older engine), Toyota launched the even moderner shaped LC100, always with a better performing engine. The Y61 never reached the success it was promised to in Europe because of it's engine. A lot of the 3.0DI from 2000 and 2001 failed. Then the reputation of these mighty 3.0 was disastrous. Another fact is that the 3.0 in its earlier version was not powerful enough for this big beast (still better than the old 2.8). 160 lazy hp where not enough for towing etc.. The needs or taste of overlanders, farmers or companies needing a trailing horse where not the main concern of Nissan. In the main time, toyota always had better solutions in terms of towing capabilities, pure luxury ( that was the gold time of big suv bought as family cars ) and look. Now, a 3.0 from 2003 and later, correctly prepared and optimized can turn a Y61 Patrol into a fantastic overland vehicle. I'm personally driving the latest version, with a completely reengineered 3.0 with Common-Rail injection (3.0CRD or 3.0DCI) What a different with the earlier 3.0… I don't have any words to tell how much I like it. But this is after a serious optimization (mine achieve 240hp and 600nm) In the same time, Patrol where selling like pancakes in Australia, because of its ultra-reliable TD4.2 and the fact that Australian where more in need of a tough vehicle.

Chassis: Chassis cracks on the Y61 are not new to me. But I never saw one personally. On mine, I welded some steel plates on the coils seats to reinforce this area… Just in case… As said RMP&O, this can happens to all sort of 4x4 when used intensively. I personally saw severe cracks on Defender 110 and distortions on 80-series chassis (not cracks), as well as cracks on a 78 chassis. Gvm is not really important in your comparison. Most overland vehicle when setup for touring will have a higher weight. 3.5 to 4.0 tons is not unusual, depending on your destinations of course. When living for destinations like the Sahara where we need at least 1000km of autonomy in the sand, both my 80 and Patrol are weighting between 3.6 to 3.9 tons. My better advice: drive according to the weight of your car, use a great suspension setup (most important thing to do on your vehicle) and if you can, upgrade your brakes. Patrols' brakes are quite soft. But again, if you're not racing, it's not a problem.

Cheers

Yeah i ment to compare the Ute in this case, because anything else would be unfair right?

They are both leaf spring in the rear right?

Well the problems mentioned in the threat only appaered with the coil spring Patrols, but i wonder why you never heard of cracked J-8 frames? They are both coil and have a comparable weigt...

@GEKO

Sorry your answer came in between. As i mentioned in another threat, i live in Europe, so patrols are not so rare here (of course never with this sweet big 4.4 engine), but the J7 in heavy durty is very rare, the j8 is in the middle, of course they are getting old.(90% of the J8 here have the strong turbo diesel)

Concerning the axles most people is asked came to the same conclusion, i had the chance to look at a J8 front axle myself and i also think you are right, so i think we can put this part aside.

With the engine it's pretty much the same thing, i guess the 1HZ engine is the most reliable of them all, but that does not concern me, since it's just to weak. The only real competition for the 3.0 patrol engine for me is the 4.2 turbo diesel from the j8. (sadly the 12HT engine went out of production so early)

It is interesting that you have seen cracks in the 78 frame, since i considered this vehicle to be the toughest due to the leaf springs (althought it has the smalles rails 145x55x4mm).

I guess to get a real answer which concept is the best, we would need a nissan patrol coil+leaf, a J78or79 and a J8 , all equipped with heavy duty suspension of comparable quality, pack all 4 trucks up to the legal 3.5 tons in round 1 and then to the illegal (over here) 4 tons in round 2 and let all 4 drive trough different kinds of terrain at different speeds. (A G-wagon would be nice to compare as well, with the big axles this one is legal up to 4.2 tons over here, but only with the 140" wheelbase)

That's pretty much what the military is doing with their stuff to see which one is the best.

I wish so done could show comparison photos between the two. I know the rear axle in the g60 that was imported into the us was pretty weak. Wondering if we got the poop end of the stick.

Yeah it's kinda interesting that the frame, the backbone of any serious offroad vehicle, is something where you won't find too much information about in most cases.

Well that tid-bit of info and link you provided is the first I have heard about Patrol frames being an issue. I did read the thread you linked to Patrol4x4.

The 80-series Cruiser has some of the same issues. Panhard mounts on the frame have been known to crack or pull away and steering box mounts have been known to crack too.

Neither of these things seemed to have been an issue on Patrol or Cruiser frames until they both went coil springs. Obviously due to the increased stress on these parts of the frames due to suspension design. The older leaf spring suspension and frames I have never seen any issues with on Patrols other than the once in a great while small crack along a leaf spring or shackle mount. On Cruisers the 60-series frames are very stout but do have an issue with rot at the rear leaf hangers as well as rot at the very back of the frames.

Yeah and as far as i know, the J6 frame is a lot lighter than the J8 frame. (130x60x4mm)

The Bremach T-Rex is another good example, the frame is kinda light, considering it is a 6ton (now 7.5 ton) truck, but its all leaf springs.

The unimog used coil all the time, but that was a flexible design, maybe that's the problem.

But as far as i know, back when the patrol was all leaf springs, the land cruiser of that era had the better axles AND stronger frame....

No sir, depending on when you are talking exactly and specific axles, ect ect. I would say FJ40's of the late 70's had better axles. In the earlier years, ie 1960's when Cruisers were coarse spline and tracta-joints they were comparable with neither being better. But the Patrols of the 1960's-70s had much much better frames. The 9.5" front diff of the FJ60's during the 80s is definitely better than anything Nissan had in Patrols until the late 1980's. But the Nissan rear axle of the 1980's, the H233 is pretty strong and the H260 is gigantic. The frames on the 160-series Patrols from the 1980's are better than FJ60 frames. Not to say FJ60 frames are bad but they have a few problem areas the Patrol frame do not have.

Any ways, they both have their + and - and both are great trucks. Had we gotten Patrols in the USA all these years I think things may be different. Alas we did not so for 99.9% of people in this country a Patrol is not an option and they know little about them.

Have you tried this same thread on Patrol4x4 or OuterLimits.com? Both are Aussie sites with members from around the globe.

Cheers
