How fast can you go in 4H?

Postby GimmieSumMo72 » Mon Dec 29, 2008 7:57 am

Not sure who left the Pathfinder in 4H (my bro or wife) but I came back from vacation late last night and rushed off to work this morning.

I didn't notice that the car was in 4H. I was flying down the Turnpike at like 85+ mph.

Just wanted to know how fast can you go in 4H and if I did any damage?


Thanks!

Mo.

Our test pilots have recorded 85+ so far. Anyone else top that?

I believe the key is not to shift in or out of 4H when moving faster than 50MPH (80KPH).

That being said, the best way to shift from 2H to 4H while creating the least wear on components is at a stop.

Uh you should only use 4H when the roads are ice or snow, in dry and rain you can use AUTO 4WD or just 2wd.

You should be able to drive in 4H all the time since its an open front diff. At least thats what i am under the impression of so correct me if i'm wrong.

The owners manual states:

Page 5-17

CAUTION
Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driving
on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.


Also on Page 5-20

The 4H position provides greater traction.
Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could
damage drivetrain components.
Speeds over 62.5 MPH (100 km/h) in 4H
is not recommended.


That should end that debate... :)

Terry, you are just one big bag of bad news. Now everyone will be walking the floor all night worried about that time they were cruzing along at 64.7 km and hit that patch of hard dry pavment!

You already have me wearing a stethoscope when I go out to start my truck!!!! LOL

62.5 mph = 100 kph (native UOM in Japan)

Actually they did round up.

100KPH / 1.609 = 62.15 MPH

Well it seems as though I have the oldest R51 on the forum with the highest mileage, so I get to experience all of the issues first! :)

Seems my lot in life, this truck is a replacement for my 98 civic, which was written off in April. It had almost 300k kms on it when she bought it. It was a reliable car, but had its quirks too.

That and I am a pretty meticullous DYIer. My Father-in-law calls me a perfectionist. Hardly, he's the one with all the duct tape fixes on his 96 Caravan....

Just call me the wet blanket of the forum.... :)
