My 2011 has had the occasional problem with longish dips in the road that let the back of the car bottom out . I shortened all the seat mounting bolts etc and painted the tips of every bolt underneath Orange so I could see what touched the road and made the scraping sound in future, none touch anymore but I still got a scraping sound when it bottoms out.
I have found the source of of the scraping sound. The trans tunnel at the rear has a heavy cast alloy lining with witness marks on the crest where the drive shaft has spun on it as the suspension decks out (see photos showing arrowed scrape on tunnel and marks on the shaft) , in fact it’s ground the alloy tunnel down a lot where it touches. My leaves look pretty flat too (see photo)and have blocks about 20mm thick between the Axle tube and the leaves (arrowed in same photo), are these blocks normal as I have not seen them in other peoples photos? Pics of my problem are attached. This will cost a lot to fix as I will need ferry my car across to the mainland and get Morgan Australia to import and fit new leaf springs for me and ferry the car back to Tasmania when it’s done (ferry alone is about $900.00) , so I need to get this right first time. it’s a 2011 4/4 with the spare wheel on the back, what spring pack will be best for me? I don’t want a hard as nails ride as we just tour in it, but I want no more bottoming out either.
