Diff On The Way Out?

I have been led to beleive that my S15 has a R34 diff on it which is supposed to be pretty strong. About 3 or 4 months ago the diff started to make clicking noises on takeoff and when slowing down. It still makes these clicks now, just a bit more frequent. I have taken it to 2 different mechanics and have come up with two different answers. One was that my diff is screwed and on its way out, the other guy just said "its a diff off of a R34, they are noisy but very strong dont worry about it." Now my father has a R34 GTT and his diff doesnt make the clicking noises >.<

Any suggestions on what it might be? serious? The one who said it was on its way out thought it was a wheel bearing at first then changed his mind so I dont know what to beleive atm.

Also just recently my car has started to make a chirping noise when in neutral. When I put my foot on the clutch the chirping stops. It is worse sometimes and then other times its not there at all. Someone mentioned that might also be the diff??

Any help would be much appreciated

There is NO way in hell the diff can make noises when the car is stationary. The chirping noise will be from the gearbox. If u drift it this will happen after a few clutch kicks.

The clicking noise is impossible to diagnose over th net. It could be a few things.

Like driveshafts clicking in the cv joints. Or there not tight enough at the wheel bearings. Could be a diff clicking from worn or incorrectly adjusted crown wheel and pinion.

Tailshaft worn or loose. Wheels not tight or the balance weights hitting something.

Brake calipers not tight. Pads are moving cause theres no shims.

Thats all i can think of at the moment.

U need to find out exactly when it happens and if it happens everytime or just once out of 10 times

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
