300E running rough/missing


The rear flex disc (guibo) is the coupler between the drive shaft and the differential. The front couple the shaft to the transmission. If it is wearing out it can make a thump when putting the car in gear, or certain driving conditions. It has nothing to do with the rear suspension. Here is a pic of the part. It's $100.00

thanks dad for puting my car through hell you jack *** total money spent on this car has been 15k in repairs by my dad rebuilt motor in 06 new brakes in 07 new belt last week. new strut work and many other stuff he payed for be for he passed it down to me now it is my problem.
However, mechanical work like that is still more than I'm inclined to attempt. Plus the car would be out of service for QUITE A FEW days if I was to try this work myself, which I can't afford. (Of course it could be out of service forever if the engine gives out). And I'd end up paying even a competent friend many hundreds of dollars anyway to do the work given the amount of time involved. Anyone I know well enough to help me for free I wouldn't trust to work on the engine any more than I trust myself.
I'd rather pull together ~$1,000-1,200 to have a new engine put in (I'd be willing to part with the car for several days to have that work done). That is, of course, if I decide to invest in this car. I've found engines on eBay as cheap as $400 with 120-130K, and got a response from junkyarddog.com regarding an engine with only 61K on it for $995--that with a 6 month warranty as well. Of course, I'm looking at ~$500 to install, so we're getting close to what I paid for the entire car. And subtracting from what I'd spend on a new car...
Well, thanks for the advice--just too scared to attempt the work myself right now. This is my only transportation for the time being, so I don't want to risk screwing it up prematurely!
btw that is total baloney that your car is worth $2,500 (http://www.kbb.com/KBB/UsedCars/Pric...izConditions=0).
I'll bet if you listed it for $3,500 you'd sell it in short order. And you could surely get another $1,000 if you're patient. Personally I'd rather get a '93-'94 LS 400 for $4,500, but for the die-hard Mercedes enthusiast, you still can't touch a W210 E-Class for that money, and '95 is the last year for the W124. I mean, it's a '95, not an '87!
So the guibo may be worn, but if it has nothing to do with the car swaying, I couldn't care less right now. My car doesn't thump or anything when going into gear or at any other time. I can accept that this annoying [hazardous?] swaying may be due to a rear suspension issue--but if that's the case, why is it so sensitive to driveline stresses while driving in a straight line? I mean, how come I can yaw the rear of the car back and forth just by hitting or letting off the gas while driving down a straight road at 60 mph?

Here is a pdf of the rear axle assembly and "Torque Strut". There sure are a lot of parts that could wear out and move. I can't even tell what everything is. The Torque Strut looks like it could be the culprit, to me.

The Best of Mercedes & AMG
I don't have a digital camera (my profile pic was taken with my camera phone) but when I get or borrow one I'll take some pictures of the car. On overall condition, I'd give my car a 3 out of 10. I'm pretty good at detailing cars, so this one looks good enough to get compliments from average-joe's when it's clean. However, the rear part of the hood is serioiusly hazed where the clearcoat is cracking, and there's similar deterioration on the roof. The paint on the top of the trunk is scratched to hell, although with the Klasse sealant glaze and 3 coats of wax I put on the car, any surface looks decent from an angle vs. looking straight into the paint. The sides are hazed/fading in places. Inside, the MB-Tex is in decent shape with no tears, although the seats are collapsing the way older M-B seats like to do. The plastic and vinyl is good, the wood trim around the shifter is in poor shape (chipped and cracking clearcoat). Electronics work fine, except for the sunroof (broken cable?) and the driver's side rear window (apparently the regulator). And the car needs an alignment, has the queer rear suspension swaying, and of course the misfire issue. And the engine has near 185K on it now, although you're right--it runs cool and maintains correct oil pressure.
My point is that I'm not 100% sure I want to invest ANY money or time to fix this now, while I've been admittedly fishing for a cheap/easy solution with this thread. You all know I could pour WAY more money into fixing up this 20 year-old fair-at-best 300E (with I'm sure only lackluster results) than I'd need to get a pristine '90-'93 300E with much lower miles. I don't like to think this way, but if I'm going to drive a 300E into the ground, at least this one was already halfway there when I bought it. I view this as much less tragic than someone trashing a really nice 300E which has a lot more going for it.
btw, Brian McL, I'm interested in your experiences with the '98 E320. Do you feel it's a good car, and how does it compare to the W124 in reliability/durability? I'm more of a BMW person, but the W210 is the #1 newer Mercedes I'd buy (not counting the W140 S-Class which I love but know can be fraught with problems).
shdoug, thanks for the diagrams. I'll investigate that torque strut ASAP. I used to work with a dealer and attended dealer-only auctions all the time. (I bought my car from a private seller, though). Prices at these auctions are completely unpredictable. I've seen decent '90-'92 W124's actually sell for $500 when the seller was a large dealer auctioning trade-ins [selling everything regardless of price] and hardly any buyers happened to be in the lane to bid up the price. I've also seen '93-'94 1st gen. Lexus LS 400's push $6,000-7,000 ($1-2K above Blue Book) when lots of dealers crowded in the lane and were bidding on the same pristine vehicle. Your E320 could definitely sell for as little as $2,500 at such an auction. However, you'd be stupid to sell your car this way (not to mention unable to unless you're a dealer). If I were trying to get top dollar for your car, I'd list it for $4,995 on Autotrader.com ("run it till it sells"--you can have it sit on there forever), on your local craigslist.org (most of those buyers are looking for deals, but the listing is free), AND in your local paper (a more expensive proposition). I'd be shocked if you had to accept less than $3,800-4,000 to sell it.
And trust me, while you can make $2,000-5,000 off a single car flip as a dealer (you could get a 2002 S430 at auction for $22,000 and sell it for $28,000 to a customer, or steal a 1995 525i for $2,800 and sell it for $4,800), it's just as easy to pay good money for a car you didn't realize had a crippling problem, or not be able to buy a car at all because all the cars seem to be inexplicably selling for more than market price on that particular day. And don't get me started about trying to sell a good car at a price that is below Blue Book, and still have idiot potential buyers offer HALF of Book value--less even than what you paid for the car--because they have no idea what the car is worth. Or try to sell a nice car at a small or no profit and have no interest at all--for months. It's not as sweet as it sounds.

Brian McL, I do love the 140's. I've driven a 400SEL and a 500SEL (both with issues). The 500SEL especially impressed me--the power and authority of a German muscle car combined with the grace and space of a Boeing 747. I love the overwhelming presence of the stying and techo-overload of these cars, what with their vacuum-close doors and trunks, power-adjustable interior mirror, double-pane glass that looks like it's bulletproof, etc. I also like how they glide off in 2nd gear and don't even feel like their moving until you get up to 50 or so, at which point the car shifts to 3rd, still accelerating like a freight train.
However, I know of major $$$ wiring harness problems, vacuum pumps going out on on the door closers, double-pane glass shattering in hot conditions--and the 500SEL had an issue where the climate control would run nonstop on full fan speed even WITH THE KEY REMOVED FROM THE IGNITION and the car locked up from outside. Hitting "0" did nothing. This would continue until the battery died. I imagine this is typical of nightmarish electrical scenarios with these cars.
I prefer the W140, but thought the W210 would be more efficient and reliable--plus it's more modern, especially inside. Did not know about the rusting issues--I've never seen one with rust (and I live in Maryland). By the time I save $5,000-8,000 I'll be looking almost purely at 1997+ 5-Series and 1996+ 7-Series, but the W140 and W210 are top contenders if I was to stay loyal to the marque.
One more thing--I heard the 1992-1993 (but 1992 especially) W140's are prone to the most problems, and the 1995 and later ones are much better. Is there any truth to this? I've noticed that 1994's and 1995's are not much more expensive (if not cheaper) than 1992's and 1993's. I'd imagine M-B got everything well nailed-down by the time the 1997 editions came out, but for the $10,000-12,000 it takes to buy one of those I'd rather have a low-mileage ~1998 540i 6-speed.
While I feel fine messing with interior bits, bulbs, trim pieces and stuff like that, the engine and other mechanicals have just been too intimidating to me so far. I guess my confidence will build with experience.
