5t341tH Posted July 4, 2015 Report Share Posted July 4, 2015 Will pathfinder parts work for the oe disc to vented disc? I've been reading around and it's mixed. I found a 94 pathfinder with all complete Quote Link to comment
orangie Posted July 5, 2015 Report Share Posted July 5, 2015 The spindle assy should work, spindle, hub, rotor and caliper. The lower control arm is different on that year, not sure where the change occurs, but it attaches in the back instead of the front. Quote Link to comment
orangie Posted July 5, 2015 Report Share Posted July 5, 2015 not sure about the brake lines because way it attaches to the caliper changes. Quote Link to comment
5t341tH Posted July 5, 2015 Report Share Posted July 5, 2015 I was lucky to find an untouched 85 D21 at the yard and compared the two. The 94 pathfinder spindle mounts differently than the D21. the LCA lower mount mounts above the spindle. So I grabbed the spindle and hub off the D21 and grabbed the 2 piston caliper off the pathfinder. I was told a D21 rotor should mate up with the pathfinder caliper. Can anyone confirm that?

I did the same conversion on my truck. If the D21 that you got the parts from had a 6 cyl, the rotors will work with pathfinder calipers. 4 cyl rotors are a smaller diameter and will not work with pathy calipers. As, a sidenote, the rotors have to be 6 cyl 2WD. Hope this helps. Quote Link to comment
]2eDeYe Posted July 17, 2015 Report Share Posted July 17, 2015 not sure about the brake lines because way it attaches to the caliper changes. You want to use the rubber lines from the swapped in caliper, the 620 hard lines at the frame will thread right in. Quote Link to comment

They all bolt up fine and I was able to test drive without crashing :D . The brake line has doesn't fit 100% but it does screw together. Just the retainer clip doesn't fit any longer. 1 Quote Link to comment
5t341tH Posted July 24, 2015 Report Share Posted July 24, 2015 Hmm I have a strange problem. I finished swapping the spindles in and it looks all good. But driving this is another story. It's terrifying to drive now. Unstable and it has a long delay between steering input and wheels changing direction. Sometimes turning it causes the wheels to squeal. Could it be a bad alignment now? Ball joints are from my 620 and are new. What could be the issue? Quote Link to comment
]2eDeYe Posted July 24, 2015 Report Share Posted July 24, 2015 An alignment should be done any time you swap out any suspension component. Also sounds like something might not be tightened all the way. Quote Link to comment
5t341tH Posted July 25, 2015 Report Share Posted July 25, 2015 Thanks. I took everything apart yesterday to see if I missed anything. Also I replaced the right lower ball joint as well. Since I had it laying around but not installed because I was lazy. Hopefully I can test drive today and see if it has improved. Strange thing I notice though, and I don't know if this is normal, but I notice that the wheel that points to the direction I am turning has way more turning angle than the other side. I see a turn angle stopper on the spindle that prevents the wheel from turning too much. Should I adjust that lockout to allow more angle? Quote Link to comment
thisismatt Posted July 25, 2015 Report Share Posted July 25, 2015 The wheels turn at different rates, with the inside wheel turning more. This is your ackerman angle. The inside wheel turns more because it is traveling on a tighter (shorter) radius than the outside wheel. This is normal, and correct. Full lock stops can probably be adjusted wherever you like as long as you don't rub or bind anything throughout your suspension travel range. 1 Quote Link to comment
datzenmike Posted July 25, 2015 Report Share Posted July 25, 2015 No that not what that is for. The inside tire will appear to be turning in more, it's normal. Set the front wheels straight ahead and stand in front. Pick one side and adjust the front wheel so that it is straight ahead by sighting back to the rear wheel. A helper is handy for this. By looking down the outsides of the tire you can get the front and read wheel pointing at you. No go over and look at the other front wheel. Does it they line up exactly with the rear tire behind it? or is it turned in or is it turned out? If it's turned in or out the toe needs adjusting. If this seems too close to call it may be ok. Raise the wheels off the ground and have someone rock the steering wheel back and forth lightly while you inspect all other steering parts. Some components will be moving but not passing this movement on (too much play or looseness) Even the steering box may need some adjustment. Quote Link to comment
5t341tH Posted July 26, 2015 Report Share Posted July 26, 2015 Ahh thanks guys. I figured out the problem. Seems like swapping the 720 spindles in severely increases toe out. After eyeballing the toe like Mike said, the car drives normally now! Quote Link to comment
orangie Posted July 26, 2015 Report Share Posted July 26, 2015 That doesn't sound right. Spindles shouldn't cause toe in/out that can't be adjusted out. Did you adjust the tie rods to make both the tires straight or did you run out of adjustment on the tie rod? Quote Link to comment
datzenmike Posted July 27, 2015 Report Share Posted July 27, 2015 The 720 knuckles are different to the 620 connection points. Bound to change the toe. Seems like he got it figured out After eyeballing the toe like Mike said, the car drives normally now! Quote Link to comment
Z-train Posted July 27, 2015 Report Share Posted July 27, 2015 The 720 knuckles are different to the 620 connection points. Bound to change the toe.I bolted my 85 720 spindles on the 78 620 drove it for a few days and then had it lined up. Quote Link to comment
5t341tH Posted July 28, 2015 Report Share Posted July 28, 2015 Really? Very weird. I touched nothing with the alignment before the swap. After swapping the spindles in, there was massive toe out. Oh well, it drives well and brakes well now so I am happy. Thanks all 1 Quote Link to comment
