Funny click: possible gearbox??

[Dirka]

Hey

mates ver6 WRX hatch

Clicking when going really slowly. Just after he lets go of accelerator, sometimes a couple of clicks, and again when he just touches the pedal to go again.

NOT cv's.

Cant "feel" it in steering wheel.

Fresh WOF with extra time to look for problem. Nothing

What say you gearbox experienced people?/

Cheers

REar diff backlash

Not uncommon at all

this man speaks the truth, had a bf5 couple years back that was converted to rwd and after getting thrashed for a considerable amount of time the diff got pretty sloppy and did the exact same thing

[Dirka]

Sounds plausible. Cheers

Front diff perhaps? It sounds like its coming from the front. . .

[Guest]

most common is rear

As normal hard to diagnoise cars over the web

give me some more details and I'll see what I can come up with for you

[Ninja8)]

and how would u resolve the rear diff problem ichi? mines been doing that for ages but still hasnt shat itself but am keen to sort the problem out. is it just the diff mount that needs replacing or is it the diff itself thats on its way out?

[Dirka]

To fix backlash, I believe you have to reset the bearings placement according to how much backlash there is/isnt.

This particular issue ended up being inner CV joint. Not outer, but inner. It has since failed, making driving difficult, particularly under braking. It did not however, stop my friend from driving to Hamilton from Picton. . . . . . . : :

yup ive done all my diff units...backlash can be set 2 ways....moving the pinion closer/further from the crownwheel (normally means worn pinion bearings) or "walking" the differential carrier closer/further from the pinion....u need to check mesh markings before u walk or move the pinion as the markings u get will tell u what u need to move...u move the pinion via shims and u walk the carrier by moving the bearings along (to walk it one way u would tighten one bearing and loosen the other)

hope this makes sense ive tried to make it as easy to understand as i can

backlash btw is the play between the crownwheel and pinion

it needs a certain tolerance (play) to allow the oil to get in there...too loose tho and u get back lash (knocking/clicking sound)

exessive backlash can severely damage the crownwheel / pinion teeth aswell
