ARB Delevoping a Locker For the r180

i could really use a locker in my m205 however...lol

Rook,
Could that be the reason they were referring to variances between different models of the R180? Newbie to this whole concept but if they could intact create a viable locked r180 that significantly increased the strength I would be very interested.

the variances they are most likely experiences prob have to do with the tolerances of the carrier...which is why it would affect the locker design so directly. i am not sure exactly what differs between a 2005 and say a 2010 r180 and it would be interesting to find out what, if any the differences are. there is no doubt a locker would increase the overall strength of this differential, however, i wouldn't personally trust it with 35's and hard use...i dont intend on crapping in peoples cereal bowls.....but at the end of the day its still not even 3/4 ton sh*t....with a 7" ring gear....u strengthen something only to find something else fail right behind it...there is always a weak point....how much can u really strengthen a small axle....jeep guys will tell u thier d30's hold up to 35s all day built but they just end up breaking housings or axle shafts locked....ive seen one go this way on the trail...its a great mess....the term polishing a turd comes to mind....it also lacks gear options or even the interest for any by an aftermarket company...still nice to see them supporting us sorry if i played debbe downer...but i personally dont trust my m205 esp if i were to lock it let alone an r180...locking a diff opens up a whole new slew of forces on the driveline, the ring gear, and the housing....

someone please explain what direct forces are placed on the housing alone that makes it weak? the housing is just that...a place for components to be functional. how would the housing fail before the spider gears?

dude...the carrier case hold the diff to the frame....and is the reason you move forward with the diff....it does a bit more than just hold in the guts. plus u eff up a ring gear the same crap could happen....lets put things in perspective...there is a reason the spiders fail...they dont just bind up...the rigidity of the casing is questionable as best. deflection of the casing in some scenarios where failure has occured causes the gears to bind up and fail..then the case breaks as the broken fragments get stuck in the ring gear. you dont alter the integrity of the casing by adding a stronger locker....

all i will say is i cant wait to see these with lockers installed. it will be very interesting. cause i have my serious doubts with the m205. i think we will see a lot sheared splines on cvs.....that tends to be a common issue with the r180 design. p

Ahh but this would be perfect for me.

I am stock, don't the 'hard' stuff any more - just would like it for exploring the back country.

Just b/c I am new to this whole diff thing as well, but what are your serious doubts with the M205? Wasn't the M205 supposed to be an "upgrade" from the R180? If that is the case, what was the point of swapping out the R180 for the M205 except for the 3.36? If available, wouldn't a 3.36 gear set get you the same place as a swapped M205? Also, if you are concerned with the M205 what alternatives would you suggest aside from SAS? Just tryin' to get educated here.

Btw, sweet rig you got there.

Thanks,

There's no question the m205 *is* stronger than the r180 ... how many failures have we seen of that diff in an X/Frontier? One? Two? A handful? Admittedly, we can't look at absolute numbers and certainly should be looking at percentages for a real statistical comparison of the two ... but I'd still take the m205 over the r180 (presuming proper gearing) any day of the week and twice on Sunday.

At the end of the day, saying the m205 is a weak diff is a bit extreme, especially since it's a bolt in mod that decidedly improves the strength of the stock drive train ... making a blanket statement saying you don't trust it doesn't really do much good without the reasons. I'm not trying to call Rook out, here, just offering a bit of perspective.

BTW, I think it's great we're seeing ARB step up and put this together for the r180 ... and I'll be watching with interest as this moves forward and folks start putting them into trucks; however, as many have said, I'll not be letting one anywhere near my front diff. That is if the r180 is still in my truck when they reach production.

when did i say the m205 is weak? im saying im not sure how it would hold up locked. energy cannot be created or destroyed. it has to go somewhere. you make one part bulletproof..something else has to handle that energy...thats all im saying jon.
