Shock absorbers leaking?

Recommended Posts

Nissan dealer states my rear shock absorbers are 'leaking' and required replacement 

 

Same Nissan dealer did an MOT 6 months earlier - no issues relating to the shocks

 

Couldn't see any leak on the video they forwarded to me of the issue and 'surprised' both shocks failed spectacularly at the same time

 

Anything I can check without jacking the thing up?

Age/mileage of the car?

 

And without getting underneath there, you can’t really tell. Tbf to the dealer, it’s not normally something that is blagged as a leak is an obvious thing, and if it’s a tiny one you might not even notice any day to day loss of damping at the rear.

At around 100k, I’d be looking at changing the dampers on any car anyway, so it’s about time regardless. The screencap is hard to tell anything either way, could be leaking at the top though from that. Could also just be dirt :lol:

That isn't where you would traditionally see a leak as that's only the plastic cover. A leak if present would be visible on the body of the shock absorber itself as per the below.

Cheers, yep, lower part looks caked in dirt and looks 'moist' - will post pictures - all this occurred both sides since the MOT in Feb 22?

 

Nissan supplied part number N56210CD325 as a replacement part - can't find anything about it anywhere - anybody know what this part number includes? - springs?

I wouldn't opt for buying a replacement from Nissan as it'll more than likely costs you over £250 for the pair. I would buy aftermarket, kyb are an excellent item. Rear suspension is a divorced setup, no need to touch the springs.

Aged dampers can fail at any time.

 

Items aren't sided

Cheers, yep, KYB kept coming up in searches 

 

Nissan wanted 266 for the parts and 237 for labour

 

Bought all four KYB corners from Amazon US import

Reckon 2 hours Nissan labour to fit?

I can check book time tomorrow, at a guest 1hr for the rears and 2hrs for the fronts as more involved. She'll be feeling great after swapping out the tired dampers, trust me.

I would say you need to utilise the old ones 

 

Yep, agree, KYB are supposed to be OEM straight swap shocks so ordered a couple of new OEM bolts just to be on the safe side

 

55269-4U00A Nissan part code for reference if anybody gets the same issue

Anybody with experience of removing the lower bolts holding the rear shocks in place?

 

Most YT videos show the bolt having to be cut off or it shears

 

Looking at buying a couple of bolts prior to fitment, otherwise going to be left without the car until fixed

 

Part number is 56280-AQ00A

My experience from last few months: nightmare. Bolt so rusted in it snapped the weld on the captive nut on the shock body and then was rusted into the bush itself which needed to be cut out (bolt and bush).

 

Had a new whiteline bush to press in and three shops failed to press. Ended up getting a second hand knuckle and top support arm from zmanalex for less than the price of a whiteline bush!

However they do look nice once done.

Also: if you do try to fit a new whiteline bush dont whatever you do heat the casing up first - not only does it warp the aluminium it also melts the bush - bt,gtts

First quote 2 hours for £200 to fit rears only

Jack up car.

Remove wheel

Remove lower shock bolt

Remove 2 x top shock nuts.

Swop over top mount.

Fit new shock.

Reverse procedure as above.

 

Probably 15 mins per side with the right tools.
