Well, back from the mechanic.
reasonable cost to install fuel filter, I supplied. -- $35
plus he weighted the front wheels with a helper jack and torqued the thrust arm bushings.
Still some shudder under light breaking.
My seller recently supplied me with a print out from his BMW dealer on all the repairs that had ever been done to my car. Neat and valuable document!!!!
In this list, I spyed replaced push struts. MMhh, What's that? did a google search and now I find out they are upper thrust arms!! They were replaced less than 20,000 miles ago!!! (tie rod ends were done - 10k ago)
so, although my front end is now a little tighter I don't think my problem was the thrust arms after all.
so, over the next year as $$$ become available I will
1) replace front struts (interested in pros/cons of lowering)
2) replace rear struts
3) replace front lower control arms (aluminum=expensive)
4) Check other suspension parts
5) Check steering box
And of course I should keep eye on brakes too.
How do you check to see if a front rotor is warped? I know they're less than a year old. Could the old rear brake rotors be causing a shudder? it feels like it's from the front.
Other things to check or look at, replace?
