Outer Limits 4x4 Board

Ok guys help me out,

As per a previous tread I was trying to pinpoint a noise in the front of my mav when either the hubs were locked in ,or the transfer put in 4h. When driven it made a funny rattle weird noise that sounded from the rhf but later sounded around the transfer ??

So now I decided to remove the front driveshaft to eliminate the transfer or c.v's etc. But now it wont make the noise at all ..

I just greased the unis and slip joint with no change in the noise and just felt the unis and seem ok ....

Any idea's ....

is it mertalic(sp?), lower in the rpm range, when turning etc??

edit, try neutralising the transfer box and free wheeling hubs, then spin the front drive shaft by hand, might be able to pick something up that way.

no it does it all the time mainly over 30klms , turning doesn't matter , tried spinning driveshaft by hand and no noise.

its got me stuffed

extra info .... didn't do it when I test drove it , and it took about 50klm of driving on the beach in 2wd but hubs locked to start making noise ....

bloody cars

what lift? ive got a six and i cant drive with hubs locked 2wd or 4wd over 40-50ks dont know why just learnt to live with it

its a 4" lift or so I was told ....... what does yours do ??

just checked by part numbers, it has superior engineering 4-5 inch lifted coils ...

mabie your front shaft is un balanced? just another idea to knock off the list .

have you check the level and quality of the oil in the transfer??
its hard to say exactly but if it took 50kms of driving i dought it would be due to the lift as this would be present from the get go. Maybe look at draining the oil in the transfer and look for stuff that shouldn't be there.

Just Mi2c

are your hubs locked in properly? if one or both are unlocked, or not locked all the way in, ya can get a rattle noise at times...

yeh they were both locked properly and locked and unlocked a few times ... may need to rip out the c.v's just to check ...

It COULD be the small needle roller bearings in the base of the stub axles... Does the slip-joint have any wear in it?

my mq shorty used to do the same thing, 4h or 4L it rattled over 25 30klms, turns out it was my front uni joint, it felt tight but when i pressed out the race cups they were had it!, just an idea to check.

couldn't feel any wear in it, but the roller bearing you mention might be worth checking as it only seems to happen under stress from the transfer , may be rolling on a different area or sumthing ???

mmm. well if anyone has a cheap front driveshaft for sale on the coast or brissy let me know , just another thing to eliminate ..

what about finding someones to borrow first then try it if it goes away then buy one or repair yours if its still there then you have not wasted money and have to look at something else

just an idea

Your unis are running at different angles as you needed to retain your correct Castor, so your front driveshaft will run unbalanced. you can usually get away with up to a 4 inch lift but for a 6 inch lift you need some serious modifications to get rid of the vibrations at higher speeds. you can fit a double carden at the transfer end and rotate your swivel hubs or pumpkin so the front uni runs straight or you could cut and rotate your swivel hubs/pumpkin so both unis run the same angle which would probably have your pinion just about dragging in the dirt. Most people put up with the inconvenience of unlocking their hubs when they want to drive faster.

Oh the joys of having modified 4bs hey ..... oh well as long as that is all it is and from what everyone has said it sounds like it ...

thanks all for the feedback ...

my slip joint made this same noise till i changed it

might get another front driveshaft to to check it out ??
