Thread: D3/D4/RRS Replacing Shocks and Airbags

The front air-springs on my D4 had worryingly deep inside cracks at 90K.

When I compared prices, the cost of a genuine air-spring without the shock was far too close to the cost of a genuine complete assembly to run the risk of having to replace the air-spring if it failed prior to requiring new shocks.

I had a leak from the front airbag about 2yrs ago. Ive just ordered some new rear strut/airbag assemblies - its just far easier to swap the whole lot out rather than having to strip the bag off the strut and replace it onto the new shock - theres no risk of finding something thats not 100% or damaging something during removal/replacement of the bag.

So no one is just replacing shocks when they wear out?

Gday Garry ,

a while back i think Redback posted a link to what is involved in changing the shocks , looks quite involved but not to difficult. I think it's more a case of finding a set of shocks to do the job . I think Terry O tried a few but was only getting minimal kms out of them . I guess the OE shocks should be available.

its certainly something that I would be interested in trying .

I replaced just the D4 shocks when the after-market assemblies became useless after only 40K kms, whereby genuine later version D4 shocks were fitted to the non-genuine air-springs.

I guess it comes down to the cost of shocks and labour to fit vs the cost of the combined unit and cost to fit. I guess the labour cost of just fitting the shocks is higher because the old shock has to be removed from the bag and the new installed - given the cost of the combined unit is not a lot more than quality shocks I guess it is cost effective to just replace the lot.

Now I dont know - hence the original question to those in the know.

Cheers

I proactively replaced my front strut assembly on my 11/2007 RRV L322 last year. On the L322 they seem to mostly fail sometime after about 10 years. As a casual observation the D3/4 seems to more frequently fail earlier. One of my shocks had failed and the other wasn't too far behind probably. The air spring on one was more cracked than the other. Labour to replace was $250 for both.
I would replace the whole assembly, no question.

I paid $600 each incl postage for OEM Britpart, which is supposed to be Delphi, from Duckworths. I would price local suppliers like Mario.

I have replaced the front air struts on my TDV8 2008. Both were changed due to an 'air' squeak. I purchased complete units, shock and air bag, due to not knowing the cars history. Fitting them myself. A pretty easy job. Providing you have an gap iid or similar.
