Hi all. Newbie here and new to this Pathfinder. Got a great deal on an 88 Pathfinder which is in immaculate shape for the year. I actually just drove it home today.
I tried the 4WD out and followed all of your instructions of how to properly go from 2H to 4h and then to 4L and back again.
I noticed no difference from going from 2H to 4H. I even stopped in the snow, stuck my head out, spun the tires and watched the front tire. It wasn't spinning like the rear but just rolling along. Obviously, 4 wheel wasn't working. My 4WD light was on though. I then tried 4L, the gear ratio obviously changed but still, the front tires were not powered.
It is a manual 5 speed and has automatic hubs. Could the hubs be frozen up or worn out? How difficult are these to take apart and diagnose? I am not sure if the front axles are turning as I would have to jack it up and get under to test. Not able to do that right now...
Any ideas? I bought this as a winter vehicle and need the 4 wheel drive for where I live. I am done getting stuck in my own driveway.
Thanks in advance.
Chris

auto hubs are very easy to take apart and put back on. there should be 6 screws around the face, undo those and hub pulls off. if I remember right there are spring clips on the hubs hold the insides of the hub, remove those and inspect the insides. if nothing is broken inside you should get by with cleaning everything inside including the hub and put back together. the springs inside are the usual problem as to loosing tension. once everything is lubed up ( I use wheel bearing grease for boat trailers, won't break down, if going in water, as fast) put back on the truck and test.
By the way, how do I know what Pathfinder I have? Mine is an 88 2 Door, V6, 4 wheel drive, 5 speed. I keep seeing references to WD21? Is this referring to the VIN number? If so, mine says W021??
Does it sound like the hub? Is this normally the problem? What else could it be that I can look into?
it could be, an easy way to test each hub individually is crawl under the frt end and turn the axle shaft ( the one going to the wheel) this should lock the hub in, if they both lock in hop in the truck shift into 4HI drive in a tight circle, the frt end will hop, jump, lurch, because of the tires trying to grab. if it does not you have a problem inside the frt pumpkin or t/case, hopefully not.
if the axles do not lock into the hub this will tell you which hub/s you are having problems with.
the VIN tells you eng, body style and general things. I think there is another place to read the WD21. I'm not proficient enough for direction on this, but I think all PF are WD21, but then I could be wrong on that too.
Are there any diagrams showing the proper assembly of the hub internals? I cannot for the life of me find a manual or diagram showing me the assembly. I think someone has had the hubs apart before.
The driver's side hub was seized and I was able to free it. The passenger side hub seemed to be ok but I still do not have 4 wheel.

was there any rust/corrosion inside? did you by chance match up the 2 hubs together and check the springs? it maybe possible that the dr. side springs are worn out.

No rust at all. They were pretty clean. Actually, I was surprised to see how clean they were. The springs "seem" fine and both look the same but without a known good one to compare to, I'm not sure. Same goes with the brakes. Not sure how they should fit inside one another. And again, I am not even sure how they're supposed to assemble without seeing a good one or a picture of it.
When I reassembled them, the outter brake piece was still on the axle shaft, I set the small one inside it and slide the hub on with the spring inside. I then just bolted them back up... Didn't see any other way to do it.

what's your email? I'll send you a PDF of the frt hub with a blow up view.
Yes, the hubs work independently of each other, but if one side doesn't lock the power will go to that hub. So, no 4WD. I would chance to bet that the brakes inside the hub are bad. I would replace both sides if it is.

I hope hope hope. Where can you find them? I've looked and looked but can only find full hub replacements,,,
