I have heard that the viscous coupling on honda awd system is a piece of crap.
Does it have a solution to replace him.
If I put a direct drive shaft, does it really affect driving on snow and on road.
I think the car will jerk a little bit with a direct system and it will be a problem because the car will be a winter beater.
I need a solution before buying my crv drivetrain

 

Honda AWD (SH-AWD) does not include a coupler, you're thinking of the RT4WD system.

Without it, its full time 4WD. You'll need to scrub tires to turn. Its not the best thing to drive on pavement, but is fine in the dirt/snow.

 

ok and does the 4wd system on a CRV is debraillable.
I will only engage it when it snow

 

No, the drive to the rear diff on the CRV drivetrain cannot be disabled, unless you remove the driveshaft. On the Civic Wagon there is a small lever on the transmission that can be moved from 2WD to 4WD using a 10mm wrench. The CRV does not have this capability inside the transmission.

 

anyone have trouble with de VC on big hp honda?
I have heard that the VC tend to slip but I want a solution.
Probably a good maintenance on the VC just like put new fluid in it will help but I need to have a confirmation before buying my kit.
I want to run about 400bhp

 

The coupler is, by design, meant to slip a little. you will not be able to refill the fluid either.

 

ok thx for the reply, I still have some doubt for the coupler but its too late to go back, Monday I have bought my Crv trailing arm, differential and 2 short axle and my friend will give me 2 spare civic trailing arm to start the project.
I will do a thread of my built if it someone is interested
