R30 Rear Shock Replacement - How To!

Recommended Posts

Just have to do this and thought i'd post it as i do it to show anyone else what they need to do (as i also have the workshop manual).

(Also posted on R31skyline forums)

First - take rear parcel shelf out!! which means taking seats out..not hard really and you could find money!!! (i found $20 in coins)

This is so you can get at the bolts for the top of the tower!


Second - chock front wheels and jack car up. (dont do a dodgy!) USE Chassis stands!!!!!


Third - You can do this either way, but i undid the bottom bolt first and levered it off the subframe, then the whole wheel will fall down onto ground (depending how stuffed your rubbers are!)


Fourth - Undo top bolts (3) and do rear bolt last as it will fall away (and go bang on the ground!)


would help if you have someone else to grab it, if so you may want to do this in reverse and finish with bottom bolt!

I will be cleaning these up so it looks like it has been worked on (for rego or roadside inspections!!)

These are the new shocks. (only pair i could find!!!) $184!!!! also got new rubbers for front swaybar, as they were easier to get!


will continue when done!

Ok...now for the rest..

clamp on spring compressors and tighten till the top insulator moves enough that the coil has no real pressure pushing against it.

*spring compressors not in the right place yet!*


*Before you pull apart look at the way the bottom saddle sits in relation to the bottom shock mount.

As i soon found out, when i tried to re-fit i found the i couldn't move the shock mount around to line up with swing arm mount with out moving the coil away from the notch in the saddle. which means i had to pull it all apart and re-position the bottom saddle in line with the top insulator bolts to line up in the car!!!!

now undo top retaining bolt (14mm) and pull off, once you've done this the coil can slip over the bump rubber and dust cover. next use a rubber mallet and whack the bottom spring saddle off the shock. Viola!!!


While these are apart clean coil and bottom saddle and repaint with your choice of colour (all i had was flat black enamel)

You should get some new rubbers with the shock kit, once you pull it apart you will see the 2 rubbers on top and under the insulator. see the difference in thickness. after 20yrs they tend to flatten out quite a bit!!

now put it all back together remembering to check where the top bolts and the bottom shock mount are so you dont have to move the coil around on its saddle!


check with the old unit to see its all in the right way and repeat on 2nd unit.


you can see here that the shock on the left has no compression at all compared to the right one, hence wheel hopping at certain speeds (mine was 90-100kph). plus dont they look purdy!!!

Now,you'll need a spare set of hands here as you cant put the unit back in AND put the top nuts on!!!


once back in and all tightened up you can clean other areas around here like the diff cover and CV joints (all help to make it clean for future inspections of any leaks)


clean and sweet, just the way rego likes it! (its not that silver under there, the flash just makes it all shiny as!)

i may add more as i need to do the swaybar rubbers yet. we'll see :happy:

    • New R34 owned here (from the US) and found a gem, '98 GTT with ~6k miles, super clean & completely stock. When shifting there's no grinding, shifts smooth, etc. The concern I have are 2 things: 1) Only in 2nd and 3rd... when maintaining a slower speed (in traffic as an example) as I let off/on the gas, the shifter will slightly move and vibrate. If the clutch is engaged, none of this happens. It's not bad, but enough to feel like something isn't necessarily right. 2) This mainly happen in 4th or 5th... the shifter slightly bounces up and down, almost like it's riding on unbalanced tires (and I do think the tires are unbalanced as I get a little of that bounce feel at higher speeds, which is maybe why it only happens in 4th/5th). Lastly, and sorry for this noob question but I want to work on this car myself, can someone teach me some on these manual transmissions? Like servicing them, best products to use, etc.; would be greatly appreciated. Thanks!!
    • Coilovers aren't even the first step. Bushes, subframe position and alignment, HICAS elimination, adjustable upper arms and traction arms in order to dial out understeer. All these things need/deserve attention first. ARBs (There's no such thing as a swaybar. Please, everybody, stop calling them that) are useful if you want to limit spring stiffness. Otherwise you can control body roll with springs. Spring and damper rates are a function of road surface, speed and usage. There is no solution that works for all cases.
    • Define "nothing". Is the starter spinning but not the engine? Engine turning but not firing? If the engine is turning but not firing, then you are missing either fuel or spark. You need to find whichever has gone missing.
    • Shitbox Tiguan updates, got the APR OTS tune put back on (no charge for it to be removed/added back), didn't want to just come in just for that (not a fan of wasting people's time for nothing) so I purchased an APR dog bone insert. The boys at German Performance Garage said they would fit it for free too since they had 1x hoist free. Now that's service you don't normally get from most workshops. Anyhow, tune back on, snow grate pulled out, dog bone insert back in and not going to lie, a few smiles when I nailed it around the industrial area heading back onto the M7. Amayama also said 1 to 2.5 month wait for the RB25DE heater hose, yeah why not, car has been off the road for nearly 3, what's a other 2.5?
    • Hmm I'm going to approach this from the other side... What is the car doing that you don't like or what would you like the car to do that is currently isn't doing (handling wise that is)
