clunking comming from diff only on hard take off???

[V8commodore_chick]

since I've had my tranny fixed I've noticed the diff has started making a clunking noise but only when I do a hard take off only, when I first heard it I thought it was just the tyres losin grip a bit but now it's getting more noticable that it's not the tyres. What does this sound mean and how much $$$ am I up for this time and whats the cheapest but decent way of fixing it? I just bloody spent $1400 on the tranny I think the tranny has to much power now for the poor ol diff

[slo_firo]

it means your diff is going on holiday, hahah make the most of it, alot of the time they spin up better at this stage

id wait till it gets real bad then just do buy another rear end - cheap frm a wrecker and easy as to repace the whole rear, like a 40 minute job if you got the right tools

[walesy]

yeh i remember back in the day when my old vl done this... couple of weeks later and a bit more flogging the diff blew... so i bought another one and spooled it... no more problems, well cept a broken axel about one every 6-8 months

[V8commodore_chick]

yeah was thinkin of buyin one from the wreckers but being a V8 they're not easy to come by in W/A . what would be a good price for a second hand one?
I told hubby when I get another one I'm gonna go out and do the bigest burnout lol I've never been game to do a decent one as I'm scared I'll stuff sommik else all the arse end bushes need replacing anyway so would be a good time to do all that too while it's out hey? I wanna get a V8 calais wreck so I can fix all the parts I need before they brake so when I need to replace sommik I've already got it but it's always the same ol setback bloody $$$$$ or lack of

[V8commodore_chick]

bloody worse thing is I haven't even flogged it to f*&k it kinda wish I had now lol make it worth while hehehe

[walesy]

hmm not sure bout price, never had to replace my vp v8 diff... but if you find a bit o cash you can get an lsd center for around the 600 mark, there is no need for a whole new diff... but replacing the rear bushes would be a good idea, it will feel alot tighter and better to drive

[walesy]

yeh but no telling what the previous owner did to it

[walesy]

go to new posts there is a vn diff for sale... i think it is a v8 one

[V8commodore_chick]

we brought it off a relly and she treated it like a baby and never flogged it but apparently they young guy that had it before absolutly flogged the gutz outa it, so it was bound to happen sooner or later

[V8commodore_chick]

Thanks walesy_5.0

The v8 ones are the same as the v6. More v8s had LSD as a factory option though.

really??? i thought the v8 ones had more axel splines??

[MyVPIsFasterThanYourVP]

are you sure the clunking isnt just the bushes needing replacing, (its a common problem that chicks need a tighter rear end!)

bwahahahaha pays to replace the front bushes aswell...

[immortality]

nothing like making sure the ass end is nice and tight, it's always better with a firm ride. do those bushes first. that might just fix your problems.

[V8commodore_chick]

will you guys keep your mind above your dicks please
I just reversed it up the ramps to have a look see and noticed alot of oil is coming out of passenger side from behind brake disc so took it off ramps and have just ripped wheel off and still have to take caliper off so I can get a better look. will tell ya later what I find, does anyone know what I will find there? or what I should be looking for?
fanks boyyyssss

[walesy]

well we cant help that our dicks have a mind of their own..

[V8commodore_chick]

also front bushes were replaced not long ago, and if it were the rear bushes making that noise wouldn't it only do it once? this does it 3 to 4 times in a row. if that makes sense

[V8commodore_chick]

well we cant help that our dicks have a mind of their own..

hehehe not wrong there but it seems to control your brains aswell hehe

[walesy]

bwhahahaha u misunderstood out dirty minds... it ok it would have nothing to do with ur front bushes... is it more of a thud noise or a tinny clunck like maybe center bearing or uni joints??

[walesy]

hang on i think i know what u mean like when u plant it from a stand still position it goes clunk,clunk,clunk?? proberly ur ring gear slipping on ur tailshaft pinion

[Mr Squishi]

I had a similar problem with a clonking noise from the back on a hard take off.

Turned out the exaust was hitting some part of the suspension (torsion bar or something the mechanic said, I dunno im not technical)when it compressed past a point, also caused a bit of vibration through the car.

checking for this problem was as easy as getting the car over a pit and having someone rock it from side to side

yep thats it it's a bit more of a chunky clunk IYKWIM hahaha I think I understood your minds perfectly lol my hubby thinks exactly the same

when it goes clunk you can sorta feel sommik slipping, first few times it happened I refused to beleive the worse and thought it was the tyres slipping on the white line lol gotta face reality sometime but I reckon it's cause I fixed the tranny the diff got jelous an wants to be fixed too

[walesy]

yeh well my old vl done that a few times and i backed off straight away, i knew what it was but it was rare for it to do it, i always used to launce it pretty hard but

[MyVPIsFasterThanYourVP]

that 3 or 4 times in a row is for each gear change? My diff does that on braking, not acceleration!
