94 pathfinder shift problem |
|
|
heres a new one for me. used to be able to shift from 2 to 4*4 hi on the
fly. now if i try it all it does is grind. come to a stop and shift it to
4*4 no problem. then tonight when i went to shift it back to 2 wh a loud
clunking noise and grinding persisted. I immediately stopped and went back
to 4*4 hi. drove all the way home in 4*4 mode. got in the yard ( safe at
home) shifted back to 2 wh drive. no problem.... still cannot go 4*4 on the
fly ( hi)
any Ideas?
Thanks
Al

They will grind big time trying 4x4 on the fly if the auto hubs are not |
already locked from previously putting it into 4wd (and not going in
reverse). All of my Nissans have.

It's best if you do go into reverse for 6-10 feet after engaging 4wd
to be sure both sides are fully locked in. The same thing goes, as is
mentioned both in the manual and on the factory sticker on the driver
side visor, for disengaging - although sometimes you may have to back
up beyond the 10 foot range to fully disengage both sides.
As for engaging, it's always easiest on the gears to come to a full
stop, count a full 2 seconds minimum then engage into your selection
of choice. Your transfer will thank you with years of service as will
your wallet. Shift on the fly at low speed for this year is,
obviously, possible but even when I worked at the dealership, we never
recommended it unless it was an emergency situation (you suddenly
found yourself slipping and it was too dangerous to fully stop, like
if someone was right behind you).
Even at low speed, you have excessive wear taking place each time you
shift in vs. coming to a full stop and taking an extra minute from
your day. Also don't forget to have the transfer case fluid changed
out (most likely with Nissanmatic-D ashless automatic transmission
fluid) if it's been a while since you have done so. It will get what
is now undoubtedly a fair amount of debris out of your case.

then whats the point of having the ability to go "on the fly"? the manual
says nothing of this . the only thing the manual does say is you cannot go
4*4 low on the fly. I know the old 4*4's with the rotatable hubs had an
issue with going at least 6 inchs prior to 4*4 engaging. BUT at any rate
thanks for the info and has anyone else out here experianced my particular
problem. I am more concerned that it may be the transfer case , tranny or
somethnig of equal expense
Thanks again

As Rob mentions below, you have to stop the FIRST time you engage 4 wheel
drive. After that, assuming you've not backed up in 2 wheel drive (to
disengage hubs) you can shift on the fly. At least that's how it works with my
'90 Path. Works extemely smoothly on my truck, and is just plain fun feeling
the handling difference on gravel roads thru the forest.

I bought a '94 new and put about 100k miles on it. It was always
difficult to get 4h engaged when I was rolling. Even with the
transmission in neutral (a 5sp), it would sometimes grind at the hubs.
It was simpler (okay, it was a pain) to just stop so that I wouldn't
ruin the hubs. If I recall correctly, the manual says you can engage 4h
at up to 25mph, but I think that is a stretch.
I never had a problem disengaging 4h back to 2wd at any speed. However,
the hubs will stay locked for a time, particularly if you're on a
straight road. After a turn or two when the front wheels are
free-wheeling faster than the rears, they will unlock. Or, if it isn't
an inconvenience, you just stop and backup several feet; you can hear
it when they unlock.
Another thing I learned is to make sure the hubs are locked before
getting angry with the gas pedal. Otherwise, the hubs will engage with
quite a bang if you're in a low-traction area. |

Oh so VERY true. And that bang just sends shivers up and down the
spine as well. :-)
