Leave the vent there, it's not hurting anything.
Nice fab job, no one would know it's not stock.


Thanks...
And as far as the vent I was just thinking about the possible gas smell just venting to open air.. its not even noticeable but I was just thinking if the gas cap acts as a vent now would that be better than leaving the vent open?

So since I know have a vented gas cap

Does that mean I can cap the tank vent.. right now It vents through a hose to a small filter under the bed....

Got the gas filler done today....
Basically 93 pathfinder...
cut the flange off....
Made my own flange that bolted to the bed.

It's possible you may need to adjust the main jetting on the carb....
This is where a wide band o2 or a dyno shop comes in handy....

Welcome. . . Nice 521.....
Use the " hot link for forum" button.... I thinks it's 2 up from the bottom on the choices...


#1529863 Lifted 521?

Posted by Crashtd420 on 17 November 2017 - 04:46 AM

I'm struggling to find a thread that outlines what a good way to lift a 521 is. Ideally about enough to accommodate 235/75/15s. And how would an l16 like that? Thanks


Ok doesn't sound like your trying to do a 4x4 lift just enough to accomodate that tire size....
First stock size tire is about 24" tall.. those are almost 29"... and kind of wide 9.3 inches . I had that size on the rear of my 521 for a while with a flatbed. But I believe a factory bed would clear them too at the factory ride height.. not sure the offset of my rims, i believe zero, but they were close to rubbing the frame in the rear. Up front they might be to much with the steering again kind of wide... up front I was running a 205/75 15.. 27 tall 8" wide....
Now I have close to the stock size height of 24" about 7.7 wide... 195/60 15....
Look up " tire size comparison" they are good to see how big the tire actually is.... and my tired L16 didn't care...

What are you trying to achieve?
Tall sidewall look or wider tires?

So regardless do you have any block spacers under the rear axle? If so remove them rear goes up.....
In the front it's can be adjusted by the tortion bars... same way everyone lowers them just opposite... same thing goes on raising it will mess with your camber some..
Hope that helps....

It was the front case that looked the same... I have no intentions of opening the diff I have....
I did the one tire in the air.... tire spun, open diff....
Also read with both tires in the air spin one if they spin opposite open , same direction lsd....
Still open...
oh well I am still learning things.. like now I know I have the 437 gears...
What that means I don't know...

The housing has nothing to do with it being an LSD or not.


Well i never do win.....
I always assumed I had an open diff, i was hopeful.... and verified yes it is open..

And by the Wayno said to count for the gearing the black diff in my truck has 4.37 gears....

And the unpainted one from the trailer has 4.88 gears

So I'll just be leaving things alone...

Not the same... that looks to have only 8 bolts ... mine has 10...

So wayno... i'm really hoping I won the lottery here ..
I've been trying to identify the 2 diffs I have.... talked with dp and he has one that looks like the unpainted one in his 71 521....

The only pics I can find that look like mine, the black painted one, say it's a h190 LSD ...
This is what I found....

I found a couple others that look the same and claim LSD but this was the best pic..
The only thing i see different is the output flange...
So does anyone know what I have?
How can I tell lsd or not?
I'll be checking the gear ratios when I get home? Will that tell me anything other than gear ratio?

Just Make sure the pic matches what you want... I've gotten screwed with not visually checking parts and just ordering because they say it's for a certain vehicle....
Not only eBay but rockauto and even the parts stores....

Gonna try and hit on everything you said...
First.... yes mine is the built l16 and even the slug it was before I liked the 71b trans behind it, 5th on the highway wasn't bad.. had to down shift to 4th on a hill but again too wasn't bad...
basically I got my 521 with a locked up trans.... i got the 71b because I wanted a 5spd, but it had the wrong bell housing on it,so I drove around with it crooked.... when I did my rebuild I bought and installed a correct working 4spd...
I almost sold the 5spd till I was told I can swap the bellhousing, which I have recently purchased... so that's where it sits waiting.. once I'm back on the road I'll do the bellhousing swap and then run the 5spd....

As far as leaf springs I'm as low as I'm going. I used the ones from the trailer because it only had 5 leafs in it, my original had 7.... I only mention them as a possible way to identify the trailer, i used them thinking they had a lighter duty spring rate...

And last the diffs....
I know there s a way to count the rotations and determine what they are...
Probably do that tomorrow.. can't find any markings....

This is the diff from the trailer..

And the diff from the truck and what I am using....

And Wayno I do have the extension on the driveside with the charcoal canister under it.....
I guess I'll look at those leaf springs and rear diff tonight... I may have been a bit quick with the comparison.... I though I counted the leafs on each pack, but now i question that... for all I know one of the diffs could have been upside down and that's why they looked different.... pics will prove....
Which of those diffs would be better? Currently using what came with the truck...
I do plan on changing my 4 speed for a short ZL71b 5spd....

That's exactly what my sender does now... :confused:


Ya seems like you get to pic full or empty... i guess its better to know your gonna run out....
I have a diagram which I can get the arc and dimensions from if you wanna try to bend your sender arm to get a closer reading.. let me know....
