remplacement du différentiel du pont R180A par un Quaife

[vincent sch]

Hy

I think you are right about the sock absorbers. Can you give me more information about the fox model you find ? Have you a reference for the Terrano ?

Thank you

FOX number is 980-02-359-A. These are for Chevrolet Silverado 1500HD, 2000HD, 2500HD. I had a long conversations with guys from FOX and two of their distributors/resellers about anything I had im my mind. These are with the proper length (I must say again - as far as I can see from the data in their catalogues), and I have asked them what valving (compress and rebound rate) is the right for me. Gave them the torsion bar spring rate and the geometry of the front syspension, along with the weights (my T2 weights 1050kg at the front and 800kg at the back with me inside and 31'tires), and they told me that the proper valving for me would be 40/80. It was pure luck that this exact shock absorber not only has the right length and nearly right mounts, but also is with 40/80 valving straight out of the factory, so revalving is not needed at all.

http://www.foxracingshox.com is their site. Go to the "OFFROAD" section, then to "shock absorbers"section, and then to "OE replacement" section, and there you can download the application guide. If you have trouble finding a distributor in France (but i doubt this can happen), there's pretty big number of resellers in the USA, and you can buy straight form them. I can tell from my experience that it is often easyer, faster, end cheaper to get parts directly from USA than EU. But you need someone in your country that have the right equipment and knowledge to be able to do the proper maintenance of the shocks, for example to refill them with nitrogen at 14bar once a year. This is to be sure they are always in perfect shape.

And, as I said, these are completely rebuildable, and each end every of their parts is changeable by its own, so in fact with the years these shock absorbers become practically cheaper than most of the others on the market.


As I said before, I will be able to check if I'm right when these arrive and I put them on my T2. There of course may be some surprises, but I have done all I can to check everything so the chance for the surprises to happen is pretty low I think.

Hi

Thank you for all this answers. I will have a look on them. And wait and see your feedback experience.

For OlivierLB, what do you think about this models of shock absorbers ?

By the way, I have just made some measurements of the upper A arms. It appears that the Calmini arms are 3.5 shorter than the originals. I have made another investigation and again it appears that the original upper A arms are with the same dimensions on all Pathfinder/Terrano1/terrano2. When we take a look at the parts catalogues, it appears that Pathfinder/Terrano1 and Terrano 2 without ABS, are using same part number for the upper arms. T2 with ABS - another part number, but this is only due to ABS cable mounts. I have measured A arms from both T2 with and without ABS, and the dimensions are the same.

So, it is pure and complete mystery for me why the hell Clmini arms are shorter.

Hi

For me it's the same mystery. For me the arms should be longer. I tested some differnent camber angles and for me the arms should be longer from 4 To 5 mm.
I think the US models are not built in the same industrie as europeen models. They are some differences between the US models and our european models. We have seen the same differences on the Calmini idler arm brace. The holes on this peace are not on the right place. It's not possible to mount the peace directly so on our Terrano. We had to modify the holes. As I said it before, the Calmini bushes are not adapted on the arm rear axel. All seems to say that the US models are a littel smaller as our Europeen models. Is their a unit conversion problem ? I think the US models are built in a other factory.

Question, if you had to realize a new kit of arms, could it be possibel that you realize two mores, one for each side, with the possibility to use the Nissan original bushes ? Can you tell me what would be the price ?

Thank you

Vincent

I believe the solution for the A arm is double:

either use the original arms with a 5~7 mm spacer over the ball joint to lift them a bit in the arc path and thus get the 3~5 mm back and keep the ball joint straighter..... (the spacers exist in Trailmaster's + 50 kit)

or

follow Sparkybg's example and fabricate new a arm that are slightly longer to accomodate the length loss/difference due to the 5 cm lift.......


PS: I don't think the WD21 and Terrano1 are from a different factory (i-e Nissan Japan) however I'm sure the T2 were produced in Spain........however due to important weight diffs in between the V6, 4 cylinder Gas engine and our 4 banger Diesels the upper a arm pivot points might have been changed in Europe....same for the steering linkage......

[vincent sch]

OK Olivier,

The weight difference between the gasoil motors and the gas motors could be a good solution to explain the differencies. In this case, I believe that the lower arm should be either shorter as the european models. If the two arms are shorter the front axel can absob more efforts on it. I think the US owners are using there 4x4 cars on more hardly roads as european owners. In this case, Nissan could have designed the US models more hardly. So we have differents between the models.

Just got a R200 front diff. The one of the flanges can be made to fit my inner CV joint. As for the other one- I still don''t know. I need to do some more measurements to be able to say.

I have done the needed measurements - the upper A arms are equal on american Pathfinder, Terrano 2 pre 1996, terrano 2 1996-2000, and terrano 2 after 2000 year of manufacture.

Here's my theory:
The Pathfinder/T1 knuckles are different. The pre 1996 T2 they are again different, and on after 1996 T2 are again changed. The lower ball joint on after 1996 T2 is different from all the Pathfinder/T1/T2 pre 1996. The kingpin angle is changed. The lower Ball joint on after 1996 T2 have about 15mm longer mount. This makes the effective lenght of lower arm 15mm more, but this is corrected by the knuckle in order to use same upper and lower arms. However, when someone lifts a T2, this makes the upper A arm travel more, compared to the lower one, and this gives a more negative camber when then the vehicle is lifted. On the pre 1996 terranos and Pathfinder, this effect is maybe less, or even opposite - when you lift a T1, the camber may become positive instead.
(positive camber is when the tyres are close to each other at their lower ends)

For the A arms - no problem whatsoever. I just need to check how much would cost the shipping to France. My price is 150EUR per pair. The shipping price must be added to this.

...as for T1, there is american line of models and european line of models. It can be checked looking as the VIN number. But really the differences between them are only in the extras. Mechanicaly they are absolutely equal.

The T2 are all made in Spain, as far as I know. Maube there's an UK facility as well, but I am not sure of this. Maybe Ford Mavericks are made in different facility also.

[vincent sch]

I think you have the good theory. You have very good knowledge of the Nissan products.

Can you send some photos of your R200A ? I hope you will send us some photos of your assembly.

Ok for the price. I will wait on the shipping price. See your PM. One question, to confirm, can I mount them with the original bushes ? Perhaps Skalraf will be interested by an other pair.
