Icon6 06 DC5 Auto - Weird rythmic pumping/clunking sound when braking for a sharp turn..

Posting as, as most issues, whether they be you getting sick or something with the car, this one popped up at 4:30pm on a Saturday. So Monday I'll be making some calls trying to get a professional diagnosis (whenever I can get it booked in.)

Just picked up an 06 Integra (RSX) Auto and have only had it for 2 weeks. Only 82k on the odo.

It's been driving fine as far as I can tell, no issues, even now. However when driving like a boy racer, coming up to a corner at 40 or 50 for no justifiable reason (not that I need one) - and try to make a sharp turn, there is a weird pumping/clunking sound and dropping feeling from the middle of the engine bay. It may sound overly dramatic, but it sounds like a nasty pumping sound, and like the engine is going to fall out or there is something loose around the middle of the bay.

Car is a DC5 AUTO, the gears are being handled by the ECU obviously. I'm just steering and working the 2 pedals.

If I drive like a granny or a dad or whatever, there are no issues whatsoever. It feels normal and safe.

I've experienced it both turning left and right sharply, just residential streets (in speed limits.)

Recently had Bridgestone RE002's put on with a full wheel balance etc. Just got a RWC. The "mechanics" were lazy ignorant ****** but thats another story for another time.

Not a car guy at all so it's all just shots in the dark for me.

I've done some googling and some clues might be some kind of hydraulic pump issue? Something to do with power steering? From my understanding of brakes on a FWD car (which is not a lot) it doesn't sound like its coming from the calipers at all, more from the middle of the engine bay.

Am planning to get it into Honda for a diagnosis, but there'll probably be a wait time there.

It's currently under a 3month statutory warranty (used car from dealer) so hoping whatever is required will be covered..

Any advice?

Thx!!

Didn't get a reply on this forum but I wanted to post the results anyway..

Took it out for a spin with a guy from the Honda workshop. Quiet chap. Demonstrated the problem, could really only make it happen when turning left (obviously my car isn't related to Zoolander at all.)

I openly admitted it happens predominately when I drive it like a ******, and when I baby it, it's normal. He said something along the lines of "well if you drive your car like this.." - I'm thinking, wtf? How am I supposed to drive it? It's not a Jazz, it's a 2L Integra auto. It's a housewives car, they need to feel like heroes when zooming home with the groceries or out to buy shoes or whatevs. I wanna feel tuff like they do!

Anyway, from the invoice:

ROADTEST VEHICLE WITH CUSTOMER TO CHECK FOR "THUMP" WHEN TURNING
Carried out roadtest with customer present, confirmed noise to be present at time of test when turning the vehicle left under load.
Returned vehicle back to the dealership.
Carried out inspection to all engine mounts, found r.h.f. engine mount to have droped (sic), also the l.h.f. gearbox mount has split.
BOTH MOUNTS GENUINE $750 FITTED.
So I'm concerned that the "gearbox mount" would be different if the vehicle is Auto or Manual, which means I could potentially order a set of mounts that wont fit my gearbox if I went for aftermarket.

I can't find any mounts that specifically say "auto" or "manual" though.

Hasport Mounts: http://hasport.com/store/index.php/m...tegra/dc5.html
Innovative mounts: http://www.shiftperformance.com.au/p...27c485a1db70a7

Can someone definitively tell me if I need auto-specific mounts? Also if the mounts for RHD and LHD are diff? (sorry for the noob q!)

Honda didn't give me the teardown on what their cost of labour is and what the cost of the part is unfortunately, but I guess I can get that work performed somewhere else.

the transmission mount for sure will be different for an automatic so you will need one specifically for an auto.

As far as LHD and RHD mounts should all be the same.

Swapping motor mounts is easy just do them one at a time.
