General Creaky Rear doors

[Jusp]

Hi, I have recently stripped my Ducato out in preparation of converting it to a campervan.
I have bought but notvyet fitted sound and thermal insulation etc, but one thing that is bugging me is that every time I go over a bump in the road there is this loud creaking noise which sounds like its coming from the rear doors. I have tried silicon spray to no avail.

Any ideas to what it might be?!

Hi, never had it happen to my van but on other vehicles I have found that this is usually due to rear suspension bushes.

You could try lubricating the rubber bushes with brake fluid to check if this stops the squeak.

Hi, I thought it was the doors creaking from rubbing or something but I will ask my local garage if they think its the bushes.

Local garage has confirmed its the axle bushes. I hope its not an expensive job!

If the rubber part of the bush is in good condition i.e. not perished and there is no appreciable movement between spring & shackle, then, as mentioned, brake fluid will stop the squeak.

Not sure about replacement costs as brake fluid has always worked for me!
