Had a bong of doom yesterday, something about vehicle leaning too much, came with a red triangle and stop vehicle and turn off engine warning so being an obedient lad I drove home, fatty seemed fine to me but after 10 mins it had left it's mark on the drive....

I had the same problem.....for me it was the ACE pipe that runs down the offside chassis rail.

My exact thought, IMHO not enough room to secure a flexible hose to prevent pressure pulses wearing the hose without removing the sub frame and then you might as well use the standard pipes.....!!! Have seen some ARB's that have had the seals go and leak, I don't think it's a rust issue, just age.... It appears that the dynamic front and rear ARB's can be replaced without dropping the sub frames but the standard ones seem to need the front subframe dropping and the rear air bags etc removed. mpirie..... ![]() On close inspection I have found this....
Look for the orange drip of coolant..... A coolant leak from the pipe to the rear HVAC unit, this is just in front of the drivers rear wheel, that is another steel pipe, this time coated in a rubber sheath to retain all that lovely salty water...!!! This pipe can be replaced with a rubber heater hose without removing the sub frame but best to do it properly I suppose.... After further reading I think I will keep it original and do both front and rear pipes, including lots of rust and corrosion treatment and prevention.... ![]() __________________________________________________ 2014 L405 Autobiography SDV8 4.4 Loire Blue Ebony interior 2011 L322 Vogue SE 4.4 TDV8 Baltic Blue.

Yep, if there is one thing worse than a scantily painted steel ARC pipe, it's a scantily painted heater pipe wrapped in a rubber sleeve to keep all that lovely salty water close to the pipe so it rusts through... |

The prop nut wouldn't shift then?

I'm not going to do a full "How to" with this as it's all in the WM and I don't think it's something you should try to do at home unless you are very brave.... Coming apart was pretty straightforward apart from the rear prop nut which, as Phoenix, surmised was a right PITA, we had two 4ft scaffold poles on the nuts and gave it as much as we dared but it wouldn't break free, it's not essential to remove it, just have to support it well... Exhaust was OK but it is heavy to do on your own...

Well done Pete! There's a fair amount of consequential work but it's worth doing and doesn't cost much more. I'd completely forgot about Tef-Gel, I'll have to dig out my tub of it soon I think... |

Great post. Following for learning as I am about to attempt replacing these ARC pipes myself too - as soon as they are in stock stateside. Their replacement seems to be super common here in the Midwest - my local dealer has two L405s in repairs right now waiting for the rear pipes too.

Out of stock in the US too. My dealer told me he has 2 L405 customers cars in at the moment waiting for the rear pipes… |

What kind of mileage do you have on it Pete?
