mechanic troubles.

[Day-mow]

so i just got my car back from the mechanic (west performance auto- Coro Valley) and i got a bill for just under $600.
i explained i was having issues with the ABS light coming on and i asked if this could be looked at. he said the FLS wheel bearing was dead and needed replacing. i said fair enough sounds important and he explained this also may of been the case for my ABS sensor not working. $119.55 for repco wheel bearing

i was also contacted about a few other things that needed repalcing.

-the hose on my rocket cover on the rear to the TB intake was coming off i was asked if that wanted to be replaced and had a Right angle bend put init to prevent this. i said ok to that it sounded important. $13.64 in parts

-apparently windscreen wipers where so stuffed and they didn't get replaced last service and they badley needed replacing (even tho i had done them at the start of winter) and so i said that was ok just to stop him from winging. each wiper was $16.60 ($33.21 total). im pretty sure their like half that from auto barn

-was charged $45 for use of diagnostic tool to sus out the ABS fault. could my X3SCT tuner have done this?

-5Lt of 15w40 oil was put in @ $36.15. ryco filter $9.05
unsure if this is synthectic but the service manual suggest a 10w30 can i take this back to him and get him to put a different oil in or do i just cop it on the chin?

-enviroment waste levy- $18.14

-Clean my K&N air filter was $16.59 (should of told him it didn't need doing cos its new)

-Injcector and fuel system cleaner -$15.91 does this stuff even work on fords???

-engine flush and conditioner as requested by me because there was a heap of sluge in my rocker cover. i would of done this my self but i figured seeing as there was a service coming up there would of been no point in doing it and then have the mech dump all my nice oil on me
-$16.32

labour total 220.63

was also told my rear RHS wheel is buckled. havn't had a proper look but bob jayne never said anything about this when i got tyres put on last week. but this probably needs looking into.

also suspects the diff pinion bearing is very close to being dead. he said its probably worth just getting a new diff. oh no we need to do a diff bring it in sometime. but it will be a pretty costly exercise and its probably to far past using an additive.

service total 599.10

is this legitimate or have i been given a run. i had to call dad to pay for it because i didn't have enough $$$ so blessed to have amazing parents but at the moment im pretty unhappy about the whole situ.

thanks for the thoughts/feedback.
