Hey guys,

yesterday arvo changed from my street tyres to my semis for Oran Park today.

So get up early this morning and off I go...not.

At first sounded like I was lazy and didnt do the wheel up tight, sounded like a clunk/metal on metal noise each few meters. (all nuts were on tight and everything)

Came back home as I didnt want to drive down 60kms to OP and have anything happen on the motorway.

jacked car up, free spun the wheels, no noise.

then took the right wheel off, couldnt see anything under there that looked broken.

put wheel back on, all tight and everything, went to park in garage, 1st gear - clunkity bang!

so its when wheel is on, under load. nothing from left hand side.

Any ideas?

I am hopeless at this stuff!!

Cheers,

Chris

Is the wheel clearing the caliper properly? Maybe youve tightened the wheel up a bit skewy and its collecting the caliper on the way through?

Checked the suspension arms? Maybe you've got a busted bush causing the wheel to sit weird...

Checked wheel to shock clearance/rubbing?

Also if you've got a hicas lock bar make sure its still tight. Grab the hicas arm and wiggle it to check for play

Heya Jon!

Yeah clears caliper no worries!

havent had a close inspection at the arms

wheel to shock clearance...dont understand!

lock bar - ah cool, will check that also!

well,

changed my rears back to my street tyre rims/wheels and so far no noise...

looking at the rims

(33GTSt rims with semis - 32 GTSt rims street rubber)

the 33 rim that was rear right seems to have a few og the weights missing from the balancing, would this have caused it?

rim looks healthy...just missing a few weights compared to the others...

thoughtS?

The missing weights won't cause problems at that sort of speed, and with a stock rim i cant see the issue being related to the wheel hitting anything (though it should be pretty obvious if you look inside the wheel well and see any shiny bits)

But, from your description it sounds like it happens once with each wheel rotation so the weights are a possibility of hitting something as the wheel turns.....

Swap the front semi to the rear and see what it does. check the strut for any marks where the weights or something could have hit the lower spring seat (i've had that problem before) also check the rotors and pads just in case something has gotten stuck in there and is destroying your brakes

yeah had Dave (T04GTAAAH) look at it, we changed wheels agai,n and no noise.

although now when I engage reverse, and goto roll back, theres a "clinky" noise. happens everyime for reverse, sounds like Im running over and breaking something on the ground.

Im starting to wonder, could my diff be giving up on me? I know it has been "open wheeling" on the track (bathurst hillclimb did it a fair bit)

Time for a new diff me thinks anyway :thumbsup:

i was going to suggest that the axle/diff teeth could be missing a couple teeth, but then u said it went away with the std tyre's on. maybe the semi is binding up and producing the noise easier? whereas the street tyre has less grip... i duno its a tough one without hearing it.

well,

each time today that noise as once Ive put it in reverse to letting clutch out to roll back, seems to get louder or its just me being a paranoid barstard!! :(

:)

well if its in the driveline....

engine mount

gearbox mount

something dead in the box (but if you can get all the gears probably not)

tailshaft centre bearing

tailshaft uni

diff backlash (not broken teeth if it was it would clunk much more often)

badly worn cvs

    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
    • You don't have an R34 service manual for the body do you? Have found plenty for the engine and drivetrain but nothing else
    • If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.
    • Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)
