Hisun Forge 450cc stuck in 4wd

[BillH]

Hi all thanks for having me.I am currently having problems with my steering system on my Hisun Forge 450cc. 

It is very hard to steer and is stuck in 4wd or diff lock.

Any ideas on how to work out what is causing this.

As I tested the bike and it is definitely stuck in 4wd.

Thanks guys

It would be harder to steer in 4 wheel drive. When you push the button to change from 2w to 4w drive do you hear anything try to happen. You might try rocking it back and forth while pushing the button and see if that might get it out of 4w drive.

It's generally the diff lock that makes things hard to steer. If the tyres and wheel alignment are in good order then being in four wheel drive doesn't effect the steering much.

Are the tyres all worn evenly ?

Have you tried backing up and going forwards again with four wheel and diff lock turned off to unload any binding in the four wheel drive ? That might get it out of four wheel or diff lock mode. You might need to go back several feet and forwards again several feet, and it's best to blip the throttle and then let it off suddenly as you are doing it.

If none of that helps I'd jack the front end up and check by hand if the diff lock is on, and whether the four wheel drive is engaged, and start diagnosing it from there...
