Hey all

Recently fitted some new springs to my R33 GTS-t to raise it's belly off the ground (Was WAY too low)

Anyway, now that I've done this, I have a suspension "clunk" issue, mainly from the front drivers side.

I've been back under the car with a breaking bar and socket, and everything is as tight as can be, but I took some careful note of bushes etc, and to me, the bush at the bottom of the shock (in the eyelet) seems to have "come out" on both sides and it doesn't look to be sitting on the pin properly.

Can this cause my "ka klunk" as I ride over bumps to occur, and what parts should I run out to order to fix it.

I'm going away next thursday, and really want this fixed.

With one of my R32s the front upper arms started making a clunking sound when they were worn. Have you got std rubber bushed upper arms in your car or the urethane ones?

When you refitted the springs did you tighten up the bushes with the car on the ground. From memory when you fit the upper arms you have to torque them up with the car on the ground, which is to ensure the twisting of the bushes(movement of the arm) is within the range that the rubber can take without breaking. It could be now that you have reset the height of the arm that there is wear in the arm from previous height or if the person who lowered the car actually did it properly you may now be forcing the arm into a range of movement that is outside what the rubber can take.

When you fit new arms they make special mention on how important it is to tighten the bolts while the car is on the ground and to me it makes sense to do the same when you alter the range of movement that the suspension arms will be going through by lowering/raising the car.

another cause of the knocking can be stuffed shocks - especially if stock shocks have been used with low springs, now that you have increased the range of movement of the shock I think it would highlight any probs the shock might have.

sorry for not narrowing the options but the above maybe worth considering.

may not be the case with you car

      So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here

      So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.

      Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go

      OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
