Front air ride suspension will not raise in cold weather. dealership tells me that the struts have worn out. the car has 52000 miles. saturday while at the dealership there were 5 other xj8 in service with same problem. before I have to spend 3100 to repair, will they fix themselves when it warms up?

a worn strut could make that noise but it could also be the strut mount its self the only true way to see if it is the problem is to remove it from the vechicle. but if you dont feel the need to do this try spraying some rust check or lubricant onto everything that you see that moves. i hope this helps.

I have 161,000 on my 00 Runner. Have had the shocks/struts changed TWICE.... (thats cause I have FUN with mine over the years) Personally, I would go with what the dealership says, then just replicate that at a good shop for cheaper price.

You might need a lube job or you may need to see if noise is coming from another place such as your engine water pump, brakes, power steering. Look for leaks.

Have an alignment performed on your vehicle, they will inspect your suspension completely and advise you of any components that need to be replaced. There is no way to tell you without inspecting your vehicle personally
