Hey i've got a wobbly left rear wheel. I noticed when decelerating (not braking) that i had a crunching noise that sounded like something rubbing on the brake shroud. It got less frequent as I slowed down, so it was definitely something rubbing.

The wheels doesnt move 'up and down' but im able to wobble it side to side by pushing on the front and pulling on the back of the wheel.

It looks like the hicas arm bush is made of jelly and so I suspect this may be causing the movement. I've got a hicas lock bar, and this seems to be tight and certainly not moving anywhere.

Any ideas?

I also found some small ball bearings on the floor of my garage around where I was working... I am not sure whether they came from my car but it was a bit weird that they were around the area that I was! Im pretty sure they are too small to be from a wheel bearing, but just in case heres a pic of what I found.

i dare say that ur wheel bearing might have let go. if u r able 2 jack the vehicle up so the back wheels r of the ground, if u have another person around get them 2 shake the wheel and have a look underneath and c if anything moves and that will tell u if its in the suspension or in the hub. also while the wheels r of the ground spin the wheel and c if u can hear any noise coming from the hub area if there is its more than likely the wheel bearing. The ball bearings that u found could b from the wheel bearings but i have never seen them just fall out with the wheel and everything on i have seen them fall out when we have been replacing them and the ball bearings can be small like the 1s u hace in the photo

Those bearings don't look like anything in the back end that i know of. They are way too small to be wheel bearings.

Wheels bearings will be conical with a tubular roller as opposed to ball bearings.

remove the wheel and brake rotor and repeat the process so that the brake shoes aren't getting in the way. The crunching almost certainly isn't hicas related.

Thanks Dave. I've checked everything again, and it seems that after putting the wheel back on that the noise is gone. I think that the wheel may have been a tiny bit off centre last time it was put back on. I've got spacers in the wheels and I think that the spacer on that side was sitting a little bit proud of the hub. Crunching noise is fixed, but I've still got a worrying amount of movement in the rear arms. Its definitely movement from the arms, not the hub. Would this be bushes that need replacement in this case?

well if the crunching is gone now then almost certainly hicas ball joints. Mine did the same thing when the tie rods ball joints got sloppy.

It's pretty obvious if you remove the inner rubber boot and move the wheel. You will be able to either hear the play due to the grease if it's not too bad, or see it if it's really bad.

Sweet! Thats almost certainly what it is then. The movement I can see is definitely in that hicas arm ball joint. Did you replace your ball joint Dave? Genuine or can you get aftermarket items?

that looks like colapsed rear wheel bearing (the hicas slop should nearly be silent, a wheel bearing will crunch)... very common on Nissans especially with huge -ve offset wheels or those put through drift or extended circuit periods.

I have a r32 so it's probably different. But i just got 2 new ones from nissan. Tried a pair of second hand ones first but they lasted about 1000kms before failing the same way.

There was mention of someone recoing theirs a bit firther down in the suspension section. may be worth looking at as the genuine ones cost 125 or so each.

    • Appreciate the feedback. It is street car, but not a daily. Last week I got a quote from a good exhaust shop for a decat, one which is bolt-on, bolt-off to be easily replaceable. I got quoted for around €150. I usually do push the motor, but I wasn't in this case to make sure that no damage is done until I get the cat sorted. I think it's best to also ask the exhaust shop for the other option and see what they can do. If (big if) I were to decat though, would it be best to tune the car or would the stock ECU handle it? As far as I know, the stock ECU is not tunable and that would require additional purchases.
    • As above, definitely bash it or get it replaced with a high flow unit.
    • get some flares on them, or wider guards haha
    • Another question sorry, what stainless do u use in the turbo external WG plumb back piping? Is it 321, 316 or 304?
    • Right, its been a while for updating this car, but I made some small but important progress today. In the end I bought an Ecutek dongle from the Australian distributor Tunehouse (for local hardware support) but have gone with a remote tune from Racebox in the US (because they have done millions of these, and I could not find any tuner where I could access the tune anyway as they are all password locked). The App is reasonably easy to work with, but the PC software reminds me of Haltech's ECU Manager that you need to use with the Plat Pro ECUs, it is a nightmare.  Anyway, I sent the details over, got back a tune file and a request for data logs. I finally got a chance to access a private test track today as they want redline logs in 3rd and 4th, and have sent them back for the first round of reviews. The main difference in the tune is going from 1.0 (stock) to 1.3 bar (19psi), although I'm sure is a lot of other stuff in the background. Keeping in mind this is a dead stock car with 125,000klm, this is what the App's performance test claimed: Before After Interesting to note that both 400m tests had the same terminal speed (158klm/h) but different ETs. And no, the speed limiter seems to be higher than that at 186kl/h. Summary of the key logged parameters for the 3rd and 4th gear runs were: Those little turbos were certainly whizzing at 200,000rpm+.  Also I'm really not that excited about oil pressure 55psi at redline so I think I'll go thicker than 5w30 (nissan recommend 0w20....) and see if that improves it. Other than that (and the big boost spike....) everything looks good as a start to me.
