#109 of 2816 acceleration info......
Dec 03, 2000 (3:20 am)
Sorry I took so long with the info. I took the time to check my info and confirm what I saw. Here goes....... www.nhtsa.dot.gov/cars/problems
1. Consumer Complaints
2. Year 2000
3. Nissan Truck
5. leave blank and press submit
You will see the first of several consumer complaints about acceleration without foot on pedal, while stopped, etc. Make sure to follow the steps or you will end up in no-mans-land. Hope this is of help. Cheryl

#111 of 2816 gonzo, don't quite understand
Dec 03, 2000 (3:39 am)
From your message, I couldn't quite understand what you were saying. You said that the "4X4 on the X doesn't work like that", but then you explain to me what LSD is. All I was trying to say was that in most (and I'm assuming in the X as well) trucks with part-time 4wd, when 4wd is engaged, it locks all 4 hubs together which causes all 4 wheels to spin at exactly the same speed. This is why you shouldn't engage 4wd in dry conditions because in turns, the outer tires cannot spin faster than the inner ones, putting strain on the system and potentially damaging it. At the same time, if all 4 hubs are locked together and spinning at the same speed, I don't see how power can be transferred back and forth between the 2 rear wheels?
I also read an article somewhere, sometime ago that explained the 4wd system in the X and I'm pretty sure that what I mentioned above is what they said it was. I may be missing something though...
#112 of 2816 Hella 500 driving lights
Dec 03, 2000 (4:05 am)
I hate to change the subject, but I'm having a bit of a problem that I thought one of you may know about. I just purchased a pair of Hella 500 driving lights and I mounted them on my Waag grill guard this morning. Tonight, I took it out for a little test and I was shocked at how high they were aimed (I must have gotten at least 6 flashes from oncoming cars). Anyway, when I got back home, I tried adjusting them down so they weren't aimed so high, but even when I adjust them all the way down, it still shoots way past my low beam range. I would be able to adjust them even lower if I install a spacer between the lights and the guard (the bottom of the lights are hitting the guard, stopping me from aiming them any lower). Was wondering if anyone has installed Hella lights (or any brand) on their grill guard and how you managed not to blind the oncoming traffic. I may just go with a spacer. Any suggestions on what I should use as a spacer (several thick washers could do the trick)?

In 2wd, I believe that the front and rear diffs allow the inside and outside tires to turn at different speeds going around corners. Only the rear axle is powered so there is no problem.
When you're in 4wd in the Xterra though, both AXLES are locked together and have to turn at the same speed because the X doesn't have a center diff. On slippery or loose surfaces, the tires can skid enough to compensate for any difference in speed between the axles as you corner. If you're on a dry road in 4wd, its much harder to skid the tires so the mechanical parts are stressed and could be damaged. The hubs themselves are not "locked" together per se.
This is why if you lose all traction at one front and one rear tire in 4wd, you can be completely stuck because without the LSD or another device, all available power goes to the spinning tire (where you don't need it.) This is why hardcore offroaders install front and rear lockers.
In low traction situations, in a sense, 2wd is sometimes only 1 (rear) wheel drive, and 4wd may become 2wd with one front and one rear driven.

Since LSD seems to be handled..
Unless the is a difference in "names", driving lights are equivilant to highbeams, and should be treated as such. They are not extra normal headlights. The aiming process is the same for aiming your highbeams, and that is most likely why you are having trouble lowering them. If you do lower them, you are defeating their purpose. If you want extra "short" light, you should have gone with fogs. In any case, auxilairy lighting should be left for the dark highway and out of the city limits.
The only way to properly aim lights is on a brick wall in a dark parking lot. I might be off with the distance, but mark where your headlights hit the wall at 6', back up 12' and aim fogs below this mark, highbeams slightly or on this mark.

Thanks for the info. This is my first 4wd vehicle, and though I'm no stranger to car components, I'm not too fluent in the 4wd system lingo. Based on what you wrote, silverxglider, are you saying that the X with LSD really can have up to 3 wheels providing power (not necessarily all at the same time) since the X does not have LSD for the front?
xcanuk, when I bought the Hellas, the box said "fog lights", but they sure look like driving lights to me. They make the X's high beams seem weak in comparison even though they're only 55w bulbs. In any case, I've decided to reroute the wiring to the high beams and use them with the high beams only. Thanks for your help.

I have a set of PIAA lights mounted and I did exactly what you said...........I used a rubber spacer so I could point the lights down....Mike

OK, short and sweet:
The front and rear differentials allow the left and right sides to turn at different rates in turns across the same axle, but without a center diff the aggregate front/rear difference in rotation cannot be dissipated (the overall distance travelled by the front wheels will be more than the overall distance travelled by the rears). This is where you need to be on a loose surface, to allow this difference to work its way out of the system by having one of the tires scrub it off by turning a little faster or slower than it otherwise would. If it can't get out, the stress builds up and something will break.
The LSD has been explained pretty well. Just remember it is not "the" solution, it will only do so much before a true locking diff would be the real answer.

for the info. But after examining the light pattern in the Hella 500 "fog lights" I've come to the conclusion that if I point them down by using a spacer, I won't be getting much help from them. The Hella 500 fogs seem to have a pencil beam pattern with a slight scatter (exactly opposite as what the box shows). Anyway, this morning I rerouted the wire to the highbeams and adjusted them the best I could without it being dark. Tonight I'll find if I need further adjusting. At least now I can drive without blinding everyone and causing accidents...
Thanks for the rubber spacer info though.
