4KQ dash speakers and front outer cv joints, etc.

[Dave <dnevin@KUHUB.CC.UKANS.EDU>]

Well, I've been going through my new 87 4000CS quattro and
I've reached a point where I have a few questions:

1. How do you go about replacing the front (in dash)
speakers? Can you pop off that little black grill or do you
have to remove the entire dash?

2. I need to replace the front right outer CV joint. It
looks fairly straight forward (I haven't gotten the bently
manuals yet--was hoping to find some used but I'm about to
give up on that)--in fact, it looks easier than the last one
I tackled. Anyway, do I need any special tools (hub puller,
spring compressor, thesaurus of foul words)? Any special
tips from someone who's done this before that might save me
hours of time and potential pain?

3. My oil temp and voltmeter guages seem to be out of whack.
They work fine when my lights are on, but when the lights
are off, my oil temp registers high and my voltage low. Is
this common? 

4. Can you replace just the antenna itself, or do you have
to replace the entire assembly. Mine is stuck at half mast.
The motor runs when I turn it on and off. I can't move the
antenna at all by hand, even when the motor is running.

Please forgive me if there is a FAQ somewhere and I missed
it (I looked, and I did go through several digests to no
avail). Thanks. I've found this group informative, and at
times, very entertaining. Makes me proud to be a quattro
owner (really. No really, I mean that. . .)

Thanks,
