these tyres are not directional.

Quote:
The tread has been separated into four ribs that follow the circumference of the tire and seem to give it a directional tread pattern, even though it is not directional.

My new jeep build is on.

I'm putting 33" tyres on my 4x4.

What i need to know:

- Do i need to strengthen the axles? How or should i use some other vehicles axles? If yes, which?

- Does the axles tube also need strengthening? If yes, how? Only by axle truss or some other option?

^^^Now before we determine ( choose ) the axle for a Jeep like vehicle ( engine : torque 25 / bhp 100 max ) we need to know, the torque delivered to the axle ( wheel ) after the total gearing . OR the max torque rating of the axle ( safe ) .

does anyone has this information ? OR can calculate it in any way ?

In my case, the engine would be producing a torque of approx 26kgn.

TRY this

find Land Rover Series 3 rear ( Salisbury ) axle ( complete assy ) , these don't break ,take lot of abuse & are full floating

OR

find defender rear & front set along with tranny , you can have AWD with this so good road manners . but need to lock the center diff while off roading .

Land Rover material quality is good , these are full floating rear & comes with CV joint in front closed knuckle. I dont see a problem with 1800 kg GVW vehicle here .

P.S. BTW where is the build up thread ?

The vehicle and the thread are in their respective assembly lines at the moment.


I don't wanna complicate matters by going LR parts way. Can someone just answer my queries and not deviate too much plz.

I would definitely suggest a truss and nice shockies to take care of that 33" load

Tejas,
I presume that you are using the jeep standard transmission. I did a quick check on the peak Torque which will be felt by the axles. If you are using 5.38 differential ratio, on the reverse gear(in the 4wd mode), the peak torque will in the order of 450kgm/axle.( 26x 5.315x2.46/4 x5.38= 457.22) If you are using 19th spline shaft, It gives an axle diameter of around 30mm. A standard shaft with that diameter can take about 250kgm torque. You need to be careful regarding the axle diameter and the final differential ratio while using a 26Kgm torque engine. I suggest you use the Bolero axle's size. I think it is 30 teeth splines and should be having about 45mm diameter which should be OK for your application. Trust this helps

Thanks.
Behram told me the same thing. He said that i can use the regular 550 axles but with 4.88 ratio to be safe since the teeth are thinner in the 5.38 and may break if i let go of the clutch quickly in 4L 1st or reverse.

Hope to see you for EXAMM! 2011 with your jeep this time around.

AFAIK only SFRA has 30 spline axle shafts, the FFRA axles still use 19 spline axle shafts. (???)

if Full Floating Rear Axle has 30 Splines, what vehicle they came with?
from when they were sold?

Tejas,
With 4.88 diff ratio, the peak torque will come to 415kgm and it lesser than with 5.88 and hence relatively safer. But it is still high for a 19 teeth spline shaft. Please have a cross check with Mr Berham on it. The spider gears are same for both the Hypoid gear sets and the axle ratios are decided by the Hypoid gears so the thickness of the splines cannot vary between the axle ratios.
