Guys,

Have had a major service and hada hicas lock bar put in. Over the last couple of days i have started to hear a knock from the back of the car when driving, sounds like somthing swinging in the fuel tank as its not constant but not sure, will have to have a look on the weekend.

Just want to see if any one has had an issue like this and what it was?

cheers,

First thing I would check is the exhaust- Specifically, make sure the mounts are still secure, or have a look at the clearance the tie-rod has with the exhaust while the car is on the ground now that the hicas set-up has been modified. Whoever installed it may have messed with the exhaust hangers or something in that area. You've gotta use pry bars 'n shit to do work on that stuff. It's tight in there too, with a decent sized 'zorst.

jack the car up, have it in gear and try to turn the wheels suddenly.. see if it makes that sound.. that will discover if its drive line related

MAKE sure the handbrake is off for this one, also try it out of gear aswell

also while its up.. shake the exhaust to see if it moves enough to make that noise

take it back to mechanic who did service. let them figure it out.

it sounds like it could be some part of the exhaust hitting, maybe the tailshaft or one of the driveshafts. That happened to a friends silvia. I think flange on cat was hitting tailshaft.

on deceleration there is no positive force/pressure on the axles. they are spinning loosely, really. Same as why i was getting diff chatter on deceleration and constant speed, but never under load.

Just see if you can get it on a hoist, and anything that moves, move it. Turn it. Shake it. Process of elimination.

Check to see if the handbrake cable hasnt come of its bracket as this can occur hitting the tailshaft

Farkin bad!!!!

Both rear tyres had loose nuts, (were not tightened after service just over 1 week ago).

Lost one nut, another 5/10 k's the wheels would have fallen off.

I didn't even check the wheels at first as it is something simple i thought the workshop would have tightened!

Called and expressed my feelings.... :whistling:

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
