[ALX5]

Hi guys
Probably you remember I asked this forum couple weeks ago about getting transmission oil and filter change vs transmission flush done at a independent shop. Anyway, they quoted me $300 at that time. Today, I brought in the X5 for them to do the service. They kept for 5 hours and called back to let me know that there are few things their technicians suggest to have done soon.
1-control arm bushing- part (114) + labor (245)=359
2-trans service- part (513)+labor (187)=700
3-drive axles-axle shaft-part (412)+labor (600)=1012
4-Wishbone link- part (240) labor (99)=339
5-drive belts- part (60)+ Labor (118)=178
6-Air filter- part (23)+ labor (20)=43
7-6,000 mile service- part (84)+ labor (30)=114. the total is over $3K.
It is a total surprise for me to see this suggestion. What are the symptoms do I need to look for if these things are need to be replaced. The guy said if I don't do it soon, it will be hard on my front tires and won't pass the safety test. I think I may ask for second opinion but the problem is where I am at there are not many independent BMW shops to shop around. Are these service necessary at all at this time. Mine is 01 X5 3.0i 85726 miles and it has been asymptomatic or I don't know what to look for.
