I've recently received a quote of $2500-plus from my Ford dealership of to fix the front and rear diff bushes on my 2005 Ford Territory. Since receiving the quote I have spoken to a friend of mine who also has a Ford Territory who had the same problem but were able to get it fixed for free due to a recall on the bushes in the 2007 model. She told me she was informed that the recall wasn't just for her '07 model, but a range of models and I'm enquiring today to see if you know any information about the matter and if my '05 model is also covered?
The recall was to inspect the front-end on the Territory when it became obvious there was a widespread problem with the front lower balljoints wearing out prematurely. It related to the early models, which included yours. It was an inspection and some balljoints that were worn were replaced, but it didn't fix the problem. The balljoints still wear and as a rule require replacement every 75,000 km or so for the rest of the car's life. There was change to the design of the Territory front-end in in 2010 and that fixed the problem. I doubt you'll have any joy getting Ford to replace the joints for you free of charge; your car is now 11 years old and well out of warranty.
