Ok this one is driving me batty.

2001 M35 141xxx on the clock

Things done so far.

- New rear rotors

- New rear pads

- Adjusted handbrake cable to stop clinking noise

- Replaced inner front drivers cv boot

- No play in bearings at all

- New tyres on the front balanced and aligned all four (rears are at 90%) no flat spots bulges tears or repairs.

- Hub centric rings on the way (car came with aftermarket 18s)

- New front ball joints on the way - boots just started to split.

I have a noise coming from the rear right (possibly front but hard to discern) its rhythmic with the speed of the car once per revolution frequency is directly proportional to speed, sounds like ffft ffft ffft ffft , almost like a nail in the tyre. Really prominent when driving next to a wall or similar.

There is no vibrations no creaks no clunks.

I have stripped each wheel back to the hub and checked and cleaned everything put it together , apart from the balljoints the the hub rings and the Nissan shaft ping when taking off everything looks to be in order.

Can anyone point me in another direction?

Im leaning towards ordering new rear bearings even though there is no noise from them no play no grinding whirring or humming.

Thank you all in advance

Open all the windows and do some hard cornering (not so fast that you can't hear from wind noise) to load up the wheels and suspension on each side to try and isolate which corner the noise is coming from.

A stone stuck in the tread? A wheel weight hitting a suspension arm?

I'd check for a stone or a foreign object stuck in the tread.

Or the hand brake may not release sufficiently. I don't know if a 35 has a drum hand brake like the S1.

I saw a BF falcon with something similar today.

I helped the owner pull it apart to find the bolts holding the handbrake mechanism had undone themselves and were so far out that they were hitting the back of the wheel studs.

Never would have guessed it till we opened her up......

Apologies for not responding promptly all.

Thank you all for your replies.

In the last few days I have stripped it all back checked every nut bolt split pin rubber and circlip , taken a steel brush to all the tyre treads. Checked in case if the steel straps on the recently changed CV boot became unraveled - nope still there all snug.

Re-adjusted the brake shoes again, checked for play in bearings shafts swaybars and links. Even looked for a wheel weight touching as mentioned above.

Nothing absolutely nothing out of place.

Then this morning on the way to the office fttt ftt ftt ftt - driving me nuts of course , and about 5 km into the trip and it just stopped ........... what the hell.

Anyway spent the last 90 min with the car on stands checked it all again - all looks good.

Went round the block no noise.

This is one weird gremlin that decided to go I guess.

I can only speculate at the moment that cause the wheel bore is bigger than the hub (until my rings arrive) that the new rotors are offcentre when i do up the rear wheel - unlikely as there is nill vibration as per my seat vibration meter :P

I hate noises in cars i.e. squeaky brakes , grinding bearings etc etc basically I cringe whenever I hear a clapped out falcodore drive past so this noise was seriously pissing me off. Glad its gone but not knowing what it was is equally as annoying now.

Thank you all once again.

      I should note too as I have all 4 wheel speed inputs to the emtron I now have the emtron controlling the attessa solenoid for 4wd/traction and launch control strategies.

      It works quite well with the adjustibility within each of the programs of the turbolamik. Essentially p1 is drive and lockup comes on like a normal driver.  But in program 7 I have customised it to not request the lockup clutch to engage until something like 6500/7 when slip was the lowest.

      Use text replace function to auto-link to referred threads?

      Yep, I like that. The tags are only on the first post of a thread and we don't get huge numbers of new threads. Also, I plan to add some more report types and we could have a member report type like 'review tags' then members could flag if they thought a topic wasn't tagged correctly.  No way man, I dig the input. Thanks!

      It's a valid thought. There's not exactly that functionality already (when creating a thread) - that's where the OP can use/create any tag they want. We'd have to come up with a way for the user to request their tags get reviewed or something. Otherwise the mods would have to review every new post's tags (for those that have them, anyway). There's kind of that functionality already exists to some extent, post facto of starting the thread, where the OP or any other user could report the post to admins, and request that tags get reviewed. We could do this already, and any user could already have made such a request. To make it a part of the forum proper, it would require an initial and an ongoing education programme, so that people know that it's a thing. OP based tagging/request for review would also require at least some (probably most) of the user base to be told that it's a thing they can do. Both of these things probably wouldn't spread too far and/or get used very much. If it was the standard approach on a lot of different sites, then it might do, because people would be used to it. Prank's approach to this differs from my original thought, by leaning into tagging. Which is fine - it's possibly better than what I originally suggested. In fact, I just went to the R32 GTR wiring diagram thread and added tags, including "Library". That's probably a good way to use tags and the idea of a library. We just have to drag together an (organised!) index of threads or posts that have that tag. I have yet to do any of my own follow up by pursuing worthy threads and posts and reporting/marking/tagging them for the library, such as the @Sydneykid stuff I was talking about, and possibly any amount of @Lithium 's and others' posts. At least if I tag them Library, we'll have a start.   Back to @Wazmond's idea as it relates to @PranK's, we might have some sort of a list of tags that are already used to scrape for this library. I'm not entirely sure how that would be presented or used, particularly if it got long. But it's yet another idea!   cheers

      Just a thought, but instead of restricting, is it possible to do like an "up for review" kind of thing? Where say someone who's not an admin/mod tags, it would require approval for it to actually tag? User posts with a 'tag' > Admin/Mod Reviews > Approves tag > Tag now exists kinda thing? Just came across this thread so Im not too sure if Im straying off topic or not but forgive me if i am...
