89 300te

[kchemers]

Just picked up a TE with a 100,000 miles on it, new ac, radiator, alternator seems to be in pretty good shape. I have a few questions,the original becker radio has a failure of the right channel, how do I get the radio out, what kind of maintenance or inspections are necessary for the rear suspension, is it too late to start using synthetic oil,( I used syn in my C230 ran 230,000 miles without a problem until a 16 year old decided to use my rearend to help her stop)
Have a slight kick sometimes between 3rd and 4th gear, previous owner told me modualtor was replaced, how can I tell, where is it, can it be adjusted, fluid looks and smells clean.

Anything else I need to check , change, adjust or watch????

Drove home 900 miles and 250 miles after I picked up the car alternator went out, lucky Freds Truck repair was able to get a replacement from Advance Auto Parts and had me back on the road the following morning

Any info, suggestions or help would be greatly appreciated

Thanks
