2003 SL500 - "Immediate needs discovered during inspection"
Let me start by saying how happy I am to have discovered this forum. I love my SL500 dearly, and there aren't that many people here in Iowa with whom I can share my passion.
I took my recently purchased 2003 SL500 to the dealer for a checkup. Following the "man, that's a nice car ... where did you buy it ... yada yada yada" conversations, they looked it over and emailed me a list of scary stuff. I was hoping to run this by you guys here to see what you think I may be able to handle doing on my own. The last car I worked on was a 1992 Buick Regal (yes, big difference ... but it took me a while to be as successful as I wanted to be). I was able to do quite a bit to it. Here's the list:
NEEDS IMMEDIATE ATTENTION
1. Reseal Left and Right PCV Covers, $250
2. Replace Left and Right Lower Ball Joints (loose), $580
3. Right front lower torsion bar is loose, $480
4. Transmission pilot bushing is leaking, replace, $100
5. Lower oil pan leaking, $1230
OTHER ITEMS SUGGESTED
1. Flush ABC System and replace filter, $520
2. Replace ABC pump pulley, $360
Some of this stuff sounds scary, but the car runs fine. The dealer tried to talk me in to trade this car in for another one of his cars, so there may be some bias involved. What do you think? Should I let the dealer do all this stuff? Are his estimates reasonable? Should I do some of this stuff on my own (recognizing that I'm pretty handy and I'd love to work on this car)?
Thanks.
Easy:
-Pilot bushing
-PCV (I assume they mean the upper portion of the valve covers?)
Medium:
-Torsion bar (sway bar link from sway bar to lower control arm I assume?)
Hard (without proper tools...):
-Ball joints
-Lower oil pan (make sure its not the drainplug leaking....)
ABC flush, big bunch of ****, dont worry about it. Same thing with the pulley, unless you can visually see damage to it somehow-I have NEVER seen one fail or need replacement.
If you have the time and have worked on cars before, most of these issues can be DIY. At a dealership parts are about 20-40% of the cost so you can see the kind of savings that are involved even if you have to buy a few tools.
There are several people on these MB forums who have done these repairs and will be willing to answer your questions. Do your research first making sure you have the correct tools, torque values, procedure etc. There are DIY articles with pictures available as well for common maintenance issues like oil changes, plugs, trans/diff service. Always use MB factory recommended fluids/filters when necessary.Some other DIY sites:

Good luck
To offer my opinion on the ABC, I must disagree with another member, the routine service will keep it in operation much longer and reduce the probability of failure, which has happened, and is extremely expensive.
If you like the service advisor/department of your dealership, I would reccomend using them, as a good relationship with a reputable service center/dealer will drastically improve your ownership experience.

It's called preventative maintenance for a reason.

2/3. torsion bar? does not have one with ABC, probably guide link which is attached to the ball joint. Have the SA show you what is wrong.
Two guide links installed is about 4 hours, don't need to align it.
4. If you can get the car in the air, the pilot bushing is fairly easy to replace.
Hardest part is correcting the fluid level.
5. Lower oil pan should only be 1.5-2 hours labor $20 parts. Plus oil
1. ABC flush takes an hour or so. Parts a few quarts of fluid and filter should be $50 I think. So $520 seems a little high.
2. what is wrong with the pulley. Never seen one replaced, it is solid metal and shouldn't go bad.
It has been over half a year since I have looked under an SL so memory might be a little off on suspension and oil pan.
I've decided to tackle the ball joints replacement and torsion bar (once I clarify what my SA meant). You guys are saying that the PCV covers would be easy to do as well, but I don't know what those are - and google hasn't given me any help. The online parts stores don't return anything when I search for "PCV covers"
I'm trying to order parts and any necessary tools before I start. For the ball joints, all the online parts places list the same options: Moog, Lemforder, TRW. Any preference?
The SA said that the ABC pulley was cracked! I don't know how that could've happened, but I did buy the car used. I'll leave that and the oil pan stuff for professionals.
There's a website called AlldataDIY that claims to provide everything I'll ever need - but I have to subscribe before using them. Has anyone here had experience with it? Is it worth it?
