Rear Axle

[JonathanPrem]

Hey guys,

In Jan im getting rear axle swapped cause i bent my hub. I found a qx4 one that im planning on swapping.

My question is Can i get another axle that has disc brake with the same gear ratio as pathfinder.

[alexf20c]

rear discs were never offered on R50s. ever.

how did you manage to bend a "rear hub"? an H233B rearend is pretty indestructible unless you were in a car accident.

[JonathanPrem]

R50 slipped will making a fast left turn in the winter with rear wheel and went in a curb that had a good amount of ice on it. axle its self isn't bent but the the circle thing where the studs are bent. Since it was a hard hit im going to replace the whole axle plus its cheaper too.

[W O T]

Im curious why youre waiting til january???

If you smacked it hard enough to bend a freakin hub Im sure theres much more damage unless you already got that taken care of.

And like mentioned, there are no rear discs for us unfortunately

Damn canadian black ice

[JonathanPrem]

I'm only waiting until jan cause my osap come in . So far i tried everything to alignment/more weight to counter balance wobble but nothing worked.

ive been asking the rear disk question 4 even and no1 had an answer, i know the R50 was never offered with rear disk,but is there another vehicle with a rear axel with disk breaks that has the the same stupid gear ratio as an R50? (4.36 is retarded,no wounder we get SH*T gas mileage)

Its not like that rear end would just bolt right up lol, MASSIVE ammounts of fab, custom driveshaft, actually custom everything, are breaks arent that bad to be worth the effort lol. Get a quality set of pads n rotors for the front. Unless you want the look of discs only

[Natedogg1701]

ya lots of custom work, but id have fun with it. and im planning on getting either brembo or baer rotars and calipers for the front, havent decided yet. only thing i hate about drums is how easily they lock up when i mash the brakes.

[W O T]

No abs?? I dont have lockup at all

[Natedogg1701]

no my abs works,but i know drim brakes will lock easier, like on dry pavement if i really slam on the brakes my rears lock nd slide,but maybe thts kus the fronts are holding real hard nd its causing the whole truk to lean forward nd lift the rear end.

Yeah, I'm always dragging my rear wheels. The drums lock up waaaayyyyyy too easily.

[Natedogg1701]

well atleast im not the only person who has that issue, the pathys stop great, mine stops on a dime and leaves change, even when the roads are wet,but really hammering on the brakes makes the rears lock right up. and off topic of breaks,does anyone else notice how Effin torquey the 3.5 is? like when the roads are wet, and you come to a stop sign or something and turn, all the tires want to do is spin, like i have to p**** foot mine to make sure i dont spin em in place, and i have brand new tires to,i think its just the motor bein torquey.

[alexf20c]

there are ways to get rear discs onto our R50s, but not worth it, IMO.

the easiest way is to swap out the backing plate for the caliper bracket from a WD21 rear disc setup. but you gotta wonder why NISSAN did not offer discs on the Xterra, Frontier, or Pathfinder with the H233B rear end.

my pathfinder stops just fine. dare i say the people that want rear discs only want them so that they can say they have 4-wheel discs?

anyway, swapping the rear to discs is the easy part. then you'll want to swap to a larger master cylinder, and either bypass or modify the rear Load Sensing Valve.

too much work for too little gain, if you ask me.

First of all, the "round circle thing with studs in it" that you bent is the axle shaft. If that's all that is bent, it's much easier to replace just a shaft than it is to replace the whole rear axle.

2nd, to everyone that complains of the rear brakes locking up too easily, take a look at your proportioning valve. It is fairly easily adjusted and sits right above the rear axle (connected with a spring). As the rear end sags (with added weight i.e. towing or from old age) it gives the rear brakes more stopping power. That probably explains why everyone is complaining about them locking up when you don't want them to.

It's unfortunate that you are so far away since I have an entire rear axle sitting behind my shop rusting away.

True but since i hit the curb pretty hard i dont know if the gears in the middle got broken/chipped/damaged. My shop told me it much easier just to buy the whole axle(400CDN) and replace it.

Two more questions- Can I replace my 02 axle with 01-04 R50/Qx4. Whats the difference between locking and un-Locking?

Btw where are you located T-morgan

[alexf20c]

since you're 4WD you need to make sure you get the same ring/pinion ratio (aka final drive ratio). replacing just an axle is easy (if you have a press for the bearings), but replacing the entire assembly is also pretty easy. your call.

I just realized that my Pathy doesn't have a proportioning valve (like the older models, the spring-type). In the FSM, it says if the line pressure is incorrect, replace the master cylinder. It seems they removed the adjustable proportioning valve completely. You can see in the following picture that the bracket for the arm is still there, but there's no proportioning valve.

you should re-undercoat your frame pwnin, that rust doesnt look to good. ive done mine twice since ive had my pathy(year n a half) i went to wallmart, got like 10 cans of rubberized undercoat, and went to town, just dnt spray exhaust or transmission. but funny thing i noticed in that pic. wen i got my pathy the underside was pretty clean actually, ledd rust than yours, but the bracket for my fuel filter was rusted right thru and broke wen i changed the filter, your bracket looks brand new, i wanna know how the fug that happens. lol

[Pwnin O'Brien]

...but the bracket for my fuel filter was rusted right thru and broke wen i changed the filter, your bracket looks brand new, i wanna know how the fug that happens. lol

Because when I changed my fuel filter about 6 months ago the same thing happened to me, the old rusted bracket just broke apart when I went to remove the filter. I got a new bracket from the dealer, of course I'm sure in a couple of years I'll have to replace the bracket again.

Haha, Nate if you think that's bad you really don't want to see mine.

It's just surface rust. If it was on the body I'd care, but a little surface rust isn't going to hurt the frame.

[alexf20c]

thank god i live in south texas.

[Natedogg1701]

your lucky you live in texas, the salt up here in new england is brutal on vehicles. its actually the reason i took the runnin boards on my truk kuz the salt n snow nd shyt will sit between the rocker panel and and the boards and rot out the body. ive seen so many vehicles with that problem. and ya i know its just surface rust, but im picky wit my vehicles and i like to see everything nice and pretty. lol helps me sleep at night. haha
