HRH Posted November 12, 2010 Report Share Posted November 12, 2010 Anybody have a Pathfinder rear end (H233 axle 31 spline) laying around from a 90-95 Pathy with the 4.375 gearset in limited slip? Checked Spaldings, nothing left in the yard. Found a 4.62 gear ratio, but that's a little too low without much bigger tires. All I need is the center section, not the whole axle. Want more traction for the hardbody. PM if you have one. Looking for under $100. I'm in Spokane. -Matt Link to comment
hessianben Posted November 13, 2010 Report Share Posted November 13, 2010 Bump for the same part !! I'm running the Pathy rear in my Frontier with the 4:6 gears with LSD H233b. Do like the LSD, but need taller gears too! I'll keep an eye out in the junkyards here, if you do the same up there. I need an '87-'90 Pathy donor with HG43 axle code. I'll keep an eye out for an HG43 out of a '90-'95. Link to comment
bagndrag Posted November 13, 2010 Report Share Posted November 13, 2010 i got a pathy im parting out but im in mass if your interested ill look to see what its got..... its like a 30 min drive to get to it since its not at myhouse Link to comment
HRH Posted November 13, 2010 Author Report Share Posted November 13, 2010 Hey Ben, that axle I was looking at yesterday was a 4.62 out of a '95, pretty sure it's all HG43 90-95 though. You don't have an H190 right? You could call up Spaldings and get that diff with the lower gears. 1-800-366-2070, talk to a fellow named Forrest, tell him you know me (Matt from NAPA) off the ratsun board and that you want it shipped. Don't remember how many miles it had though. The only downside is shipping may be a bitch. Link to comment

Of course a shipping quote is needed, I'm betting those suckers are heavy. Link to comment
datzenmike Posted November 13, 2010 Report Share Posted November 13, 2010 Just like the 720, there's an aluminum tag on the inner pass side fender below the hood hinge with the axle ratio stamped into it. WD-21 Pathfinders and D-21 Hardbodys have them. The ratio is stamped on the lower right hand side. I've only seen two sizes HG 4.375 and HG 4.625. HG 46 is the 4.625 ratio: It isn't marked if it has the LSD option but if you take a rag and wipe the oil/mud of the back of the differential, there will be a bright orange sticker about the size of a postage stamp if it does. They look like this: The diffs themselves are.... massive, slightly larger than the Ford 9". . Link to comment

WD-21 Pathfinder 31 spline compared to 620/720 H-190 with 29 spline. . Link to comment
HRH Posted November 13, 2010 Author Report Share Posted November 13, 2010 Thanks Mike! I started doing some gear recalculations using 4lo.com and apparently with even the mild 30" tires over stock on my hardbody, I would need 4.55 gears to equal stock ratio, so actually the 4.62 gearset would probably still yield better mileage even though turning at higher rpm on the freeway, just because it would have the gearing to push the weight of the truck since I only have the low hp KA, not the torquey VG. So what I may do is go find a 4.62 Pathy and just grab the front and rear diff and do both. More of a pain, but oh well. Just have to do some checking at work and make sure the halfshafts will fit up to the flange on the front diff. Pretty sure they will. Link to comment
HRH Posted November 13, 2010 Author Report Share Posted November 13, 2010 Okay, just did some checking. The front diffs are the same between hardbodies and pathfinders from 90-95, BUT the halfshaft flange is different as is the outer spline count. It's 28 through the hub on V6 and 27 spline on 4 cylinder and the inner flange is a 6 finger on the V6 (looks like a Chevy halfshaft) and a round 3 position with 2 bolts each position on the 4 cylinder front R200 diff. SO, that means as long as I change out the flanges on the diff from a 4 cylinder truck, it'll work just fine, which means both diffs will fit and work without much effort. I don't think the 4 cylinder trucks got the 4.62 ratio though, only the V6s. So anything from a Pathfinder or truck in the front will need the diff flanges swapped out to keep using the 4 cylinder front axleshaft. I should change this thread title now and move it out of for sale, since it's turned into a research thread. :) Link to comment
hessianben Posted November 13, 2010 Report Share Posted November 13, 2010 bump for a useful thread! Matt- I'm running an HG46 from a 1988 VG30i 4x4 pathy. The 1987-1990 H233b housings have 9 bolts on the 3rd member (Datzenmike correct me if i'm wrong) and the later trucks had 11 bolts? Which year is your housing from? Link to comment
datzenmike Posted November 13, 2010 Report Share Posted November 13, 2010 Wow, up to Aug '89 they are 8 bolt and 11 bolt after. Or all '90 and on are 11 bolt diffs. Did not know. Mine is obviously an 8 bolt. Link to comment
Icehouse Posted Monday at 01:26 AM Report Share Posted Monday at 01:26 AM I need one now. I have the 33 spline LSD.... I need the early one. Or are the later axles 33 spline the same length? Link to comment
