Outer Limits 4x4 Board

Hi i've just installed TG 6.5's in to my zook and they are really whiney in high range when you back off the accelerator.
Im just wondering if anyone else has had this problem? i only installed them yesterday, i've just put it down to new gears, because i thought being new they might have to "bed in"
Im running VMX 75-85w castrol oil in the transfer, but im going to drain it it about 500k's, im just wondering if i should put some oil stabiliser (morey's or lucas) in their when i change the oil?
Thanks Mitch

I've got 6.4's and they whine on the high way .. i would presume its simply because the gears have more contact (more teeth)

Mine trailgear whine alittle more then stock..But 5th low whines like a bitch.

my 6.5 whine in low at high revs, and are a little bit louder in high. gotta make sure you grind the right amount out of the case

my 5.14s whine heaps too - low range you can hear the whine over the engine... as in, you cant hear the engine =)

keep in mind the gears are spinning faster than the old ones too...

Did you put oil in the case?? someone had to say it

Someone didnt read the original post good enough Someone had to say it

up yours blue suzi i 'skimmed' over the post, jumped to a conclusion and wrote it regardless haha

what about trying a thicker oil?

same thing is getting talked about on pirate

in low first with 6.5s my mates think the zook sounds like its hydraulic drive moves so slow and all you hear is a whining noise.

get the wife to hop out and see if the noise go,s away

hahahahahahaahahahaahahahaahha

thats exactly it the gears have a different tooth pattern on them to the stock ones and are wider as well, some brands more than others. You wont even notice it after a while, although any passenger you may have will be worried about all the crackling and whining sounds hahaha

t/case gears noisy.....naaaahhhh. thought they were the beez neez. don't forget when they are installed precise measurements need to be taken of the case and other components so that the correct shimming can be done, some thing people usually don't worry about.

Who said they're not the beez neez?

My 6.5 TT's are quiet - my gearbox/tyres/motor/rattles and squeaks are far noiser than the transfer.

Steve.

just been through the trail gear 6.5 instructions and it seems they have left out the shimming sequence. for thost that want to know i'll see what i can dig up at home. if the shimming is done correctly it will get rid of heaps of noise.

I could let you all borrow me hearing aids, when you switch them off, zooks sound great

So what do i do about it? just drive it and hope for the best?
Mitch

would be keen to find out specs on shimming gears. mine is too loud in low range, and is louder than stock in high.

ignore my hand-written anotations.
