Hatch sti 08 front shocks
 

Hi
My sti hatch has developed a slight knock from the front suspension when going slowly (under 20mph) or when reversing. I've changed all bushes and the droplinks but still have the noise. I've been trying to source some front shocks as I'm thinking that's what the knocking is now, I just called my local Subaru dealer and they quoted me £388 per side for just the shocks! To me that sounds a lot. I then tried all my local auto factors and none of them stock or can get shocks for my car. Does anyone know where I can get some cheaper front shocks? My only other option is coilovers which I'm not sure about as I've heard they can cause the comfort of the ride to be reduced.
Cheers

How many miles does the car have?
Jack up the car and hold the wheel from the 12-6 position and see if there is any play. If not it probably isn't the shock.
Does the knock happen even on smooth roads?
It could be the top mounts, too.

The cars done 74000 miles. Yes you can hear it on smooth roads, mainly hear it when reversing on to my drive though. Changed top mounts a couple of months ago.

Fair enough and at that mileage I guess they have seen better days.
Importing from US despite postage and tax can sometimes work out cheaper: https://www.subaruparts.com/

I just can't believe how much replacement shocks cost and it seems strange you can't buy non genuine shocks for the sti hatch. Maybe coilovers are the way to go?

i should be removing my Sti suspension in the next couple of weeks to put coil overs on so mine will be going up for sale

That could be a plan. Just out of interest, what coilovers are you going for?

I got my rear shocks from adgespeed. Came off a delivery mileage car being prepped for rally. Paid £120 a corner.

I'll check them out. Thank you very much for the info, could save me a few quid!

Got a set of BC's cheap so will run with them for a bit and see how they hold up , don't use the car as much these days so the ride shouldn't bother me to much

I'm putting ohlins on mine over next few weeks me my jdm struts and springs will be up for sale too

How much would you want for your struts and springs?

I'll be asking £150 for all my 330s suspension fronts and rears

Has anyone else experienced front suspension knocking on an sti hatchback? I've read a couple of comments on it but it seems very rare!! I've changed all front bushes, droplinks and the strut top mount. Can think what else it could be other than the shocks. The knocking doesn't affect the performance of the car, it's just annoying!!
Cheers

Have you got a chance to check for any play at 12-6 o'clock with the wheel in the air as mentioned previously?

Yes I checked that and it has no play on both sides. I have noticed that if I stand by the side of the car and rock it from side to side I can hear a slight knock/click. Could that be linked to the noise I get when driving?!

You need to lift the boot cover and get someone to feel for play between the shock's stanchion/piston and the shock body while you shake the wheel.

I'll try that tomorrow. Do the symptoms sound like shocks to you or could something else be causing it?

I can't say and only ask to check the above from experience. If there is play between the piston and shock's body it means that the shock's bush insert has worn and you should be able to feel it and perhaps hear it when you do the above test.

I had a knocking (sounded like plank to plank) when going over road undulations at slow speeds that drove me mad and it turned out I had forgotten to fit a rubber washer between the IC undertray and the bonnet!

I checked again today and there is play between the piston and the shock body, I suppose that means new shocks are needed!?!? Both sides had quite a lot of play..
cheers

That's not good but it seems you have nailed the problem now.
