More likely to be uni joints. The sudden transfer of acceleration or deccelaration will cause a old uni joint to clunk. Get it looked at i guess. Uni joints can be a dangerous thing if they let go, especially the front one/.......dig in a weeeh pole vault

Mine does it and it sounds a lot like diff slack. Its pretty normal for a car thats had a bit of a hard time or done 150,000kays.

Mine started doing it around 120,000kays. Nothing to be worried about the Lines are as tuff as nails. I've been poping the clutch since day one 60,000kms ago and nothing has broke.. :) Gearbox whines a little and diff clunks a little (only when a little rough with accelerator or gearchanges)

Lol.. Have you driven a ford lately.. My old mans Auto ford used to do it all the time.

Wouldn't worry about the uni joint as the split tail shaft is there to help save your arse if it lets go.. I've heard story's about the old single piece tail shafts letting go and lifting the car in the air.

my 32 dose this also, i can hear it when i take off slowly, it sounds like there is some play between the cogs in the diff. but i thought it was from me being a dic!< head once and letting the clutch out too soon while the "E-BRAKE" was still on a bit when i was getting sideways?!

All of my diff cradle bushes, those for the entire rear end K-frame are knackered and it makes a loud clunk when backing off. It's got progresively worse over the last year. Nissan quoted me $3000 to fix it with an entirely new K-frame from Japan... I decided to go a second hand jobbie for now (much cheaper!)

the little boomp you all hear when u pump ur accel at 70 ish is a slightly worn diff....nothing to concern you at all...if you get it lapped it will prolly fix it...but there isnt much point.......its nothngs...forget its even there.........if it annoys u...fix it. it is just minor slap between the teeth of the crownwheel and pinion.........

I've owned a few cars and the line is definately the toughest.

Gearbox (even though the RB20t is the weakest of them), diff & chassis are damn strong.

Lol.. My old VS within 9 months broke the rear IRS chassis from the diff mount, gearbox went as did the Diff.

If my gearbox went today I would be happy as it has lasted so damn long with lots of second and third gear snaps.

Have faith, the Lines are a tough car, just drive it and don't worry... :(

My diff has always clunked a little. Even my dads patrol does the same and its been babyed since new.

Take it from me you won't break the diff easily. My dif is quite worn now as it doesn't pull two wheelers anywhere as much as it did. Mainly me being bad to it.That problem should be fixed soon as I have a cuso 2 way centre at home.Cant wait to get it in hehehe. I can't beleive how well the old diff is putting up with the bashing I give it.

      Stagea Front CV Axle Question

      Man, different parts but the same numbers is terrible @dbm7! And it doesn't help that most online shops don't list the part numbers at all. They just give a list of compatible models...

      Slow when hot could also be because its getting more dynamic compression, OR things are getting a bit tighter once it is all expanded. If it were an earthing issue, typically I'd expect you to have it have issues all the time. Unless it's really a combination of both things. Where the higher compression, and things being a bit tighter, is giving that bit of extra load and you do need a slight clean up on the cables/connections.

      Stagea Front CV Axle Question

      Yeah, this is one of the most annoying things about nissan part numbers... I've got an unrelated example... Image is of the AT output shaft ~ they have the same part#, but clearly the shaft on the left is beefier design to that on the right ...the difference (essentially) is the 'lighter' shaft on the right, is for engines up to RB25DE (this includes RB20 variants) : the shaft on the left is for RB25/26DET(T)....are they interchangeable? Yes...but obviously one shaft is going to be stronger than the other...and, the lighter shaft is around USD115, but the heavier shaft closer to USD150...same part#... ...epc-data usually tells a tale ~ the amayama listing for 39100-23U60 has a note "Longest side is between 60 and 105 cm" ; no such info is there for 39100-23U70 ...and given the great disparity in price between the 2 parts, it makes me at least curious (to the point of caution) where the 'extra money' went? ...ie; these 2 parts have a cost difference that (to myself at least) isn't explained by 'plastic boot'...ie; with amayama there's AUD700 price difference ...plastic versus rubber?...I'm not seeing it like that...and 60cm ~ 105cm...??...that's a huge disparity....something hinky going on here... I'd try searching by VIN, not model... /2cents

      I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.

      One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
