W126 300SE front suspension and steering repair.

Post by dreadnought » Tue 04 Jun, 2019 9:48 pm

I have been looking at the front end of my 1988 W126 300SE, Due to age and obvious wear, I have decided to replace the Front Guide Rod Track Strut Mounts and various other rubber bushes, is there a step by step guide for the correct procedure to perform this task, I am fairly competent on the tools and confident I can do the job but I haven't worked on Mercedes vehicles before. Also, a supplier for bushes, they do not have to be OEM but at least the close to the same standard of manufacture, I am not likely to wear anything out in a hurry as in this vehicle, I only travel about 2000 km per year.

Hi Dreadnought

Can only assist with suggestion about parts. I often use the Pelican Parts site in the US to identify which parts were original equipment. The site also gives a quality rating for the various parts available from manufacturers. Once I have that I track down the suppliers who handle them. Happy hunting.

Hi Dreadnought

I see you are not being overwhelmed with responses.

I refrained from giving advice on the grounds I am not as well versed on mechanical repairs to front ends.

In light of the poor response I will proffer some more info.

I have found the company HSY to be a good source of parts at a reasonable price, the other is ASV.
Both of these I believe have outlets in Melbourne. Whether or not they have OEM supplier parts you would have to ask.
When the exchange rate is good I buy from an American company called FCPEuro who I have had good experiences with.

As to performing the work I can say the W126 is well designed and not a complex vehicle to work on.
I have found info on the internet for all the work I have done on mine.

If you need some direction Craig Baulderstone a forum member her in Adelaide is extremely knowledgeable on W126.
To be honest I am surprised he hasn't responded to you as yet.

Regards
Paul @ Beefa

yep - a more difficult answer and didn't get back - step by step guide is in factory manual that you can get on cd, but sometimes you find bits of it reprinted online. I would suggest googling and look for youtube etc. Its not something i know off the top off my head and that's what i would be doing. But any work i have done, its all pretty straight forward and although it might look a bit different, I don't think there are any 'tricks'. And agree with Beefa on sources, price the local sources and then just google - US look at fcp \euro, pelican and autohaus.az. - the latter being good I find to get part numbers etc to then use in searches.

and i forgot - the only tricky bit is you need an internal spring compressor. Aftermarket can be bought relatively cheaply but they don't wear out and you might find a friendly local to lend you and/or offer a nominal contribution to their purchase costs.

Hi Maurie,

If it's not too late, there are two sets of genuine Mercedes guide rod mounts available at the following link for just over AU$172 each, including postage, and the seller is open to offers. Obviously, you're going to have to add another 10% to whatever price you agree to, for GST, but that's still a good deal.

https://www.ebay.com.au/itm/Genuine-Mer ... SwEB5c4~Ei

The information at the following links should help:

Hi Maurie,

Further to my previous post, obviously it’s best to use Mercedes parts if you can afford them, but, when it comes to suspension parts, Lemforder is the next best option.

Although they’re usually a lot cheaper than genuine parts, as you can see at the following link, Lemforder guide rod mounts are more expensive to buy locally than the genuine parts I linked to in my previous post:

https://www.ebay.com.au/itm/Suit-to-Mer ... ctupt=true

Prestige Auto Parts mainly sell Lemforder suspension/steering parts, and they’re usually reasonably priced, but in their listing for guide rod mounts they’re described as Unbranded/Generic. They are, however, listed as OEM so it’s worth asking them what brand they are:

https://www.ebay.com.au/itm/Mercedes-Be ... ctupt=true

Prestige Auto Parts also have FEBI guide rod mounts and they’re listed for less than $120 including postage:

Thanks for all the replies, I really appreciate the help and positive responses, after some research on the net, I think I have my head around the front suspension and steering now. I have only one question left regarding coil spring compressor. I have seen the internal Mercedes one, how does that compare to the external spring compressors that hooks on the coil from the outside, I have an old pair of that style and wondered if they could be used.

No, there's not enough room to grab enough of the spring to compress it enough to get it out. Its a fairly long spring.... and partly why they have such a great ride! They are a funny tool - make the job so easy but you pay the money and then only use them once every 10 yrs or so. Great when there is a local with a set you can borrow. From memory they can be had for less than $200, which in terms of the time it saves you or how much a workshop charges for time, its not so bad.

The only spring compressor which works is the internal one; they are available for about $150-$200 on-line locally and work well. Find a local fellow OZBenzer who will lend you theirs or you can borrow mine. I'm in the Northern Grampians, VIC. Don't use the standard outside/clamp-on spring compressors, they will either let go or more likely you won't be able to extract the spring.
Cheers, Erik.

I know its been done.... but makes me really nervous - mainly knowing the brackets wont bend or slip, but also I don't know how much force some Bunnings threaded bar will take, but that's possibly ok. But i get the suggestion is to leave in place so you can work on the basis if it does let go, that it will be contained. The way my brain works though, I would add up the time to go hunting for the bits and making them, consider the risk too, and then go for the right tool. Its a shame Ozbenz doesn't have a bigger active community like it used to.... would be more likely you would get locals offering to lend theirs. You could try the question on Ozbenz facebook..... you never know.

Buy the proper internal spring compressors, even the cheap ones on eBay are much safer that screwing around trying to use some dangerous makeshift alternative.

I bought a set like these https://www.ebay.com.au/itm/Coil-Spring ... Sw2gxY1hh4 and have removed and replaced numerous sets of springs on W126's.

Also, if you havent bought the guide rod bushes yet, buy one of these complete sets https://www.ebay.com.au/itm/Mercedes-W1 ... 1c1e672d27 I purchased one of these for my 560 SEC and for the $800 or so inc shipping was able to rebuild pretty much the entire front end. Great quality, I installed it all over 3 years ago and its still perfect.

I opened your link Dean - that looks like mine and I've lost count of how many times i have used it and lent it out. But at the bottom of your link is this one https://www.ebay.com.au/itm/New-5pc-Coi ... 0008.m2219
Still looks the same, is in Australia and at $84 is the cheapest I've ever seen.

Yeah I saw that about .9% negative if you work it out, not particularly worried. Don't forget about Ebay protection, it's worked well for me in the past.

It's easy for anyone to sit there and sh*t on suppliers and parts that they personally haven't dealt with, and rely on internet commentary from others that may also not have first hand experience with the supplier or the parts.

Its good getting info because there is crap out there, but then the hard part is sifting through the armchair experts and those with real experience. We've known Dean for a long time and seen the quality of his resto so I value those judgements. I guess we don't know the 10 yr test for which is best, but just because something has a benz part number, doesn't guarantee its better quality - Benz don't have a rubber factory and make their own parts.

And you will be able to report back on the spring compressor - mine is chinese but its not rocket science - good strong bases and a thread and it works and just thinking of the cars I have replaced 4 springs into, it must have done about 50 compressions, not counting all the times I have leant it out . Also some people don't have sympathy in using tools and understanding how a tool works and exercising a bit of care can help and being a 'bull at the gate' can break things and produce bad reports. Once again its hard to know unless you know the person making the remark.

Glad to hear you had a good experience with the parts and the seller Dean. Obviously, others haven’t been as fortunate as you, hence the numerous negative reviews out there.

Yes, it is easy to convey opinions, whether our own or others’. I think most will agree that doing so, in the interest of balance, and to encourage others to do some research before they buy, is a good thing, especially when dangerous failures have been reported. To that end, I just said the parts ‘may’ be dodgy, because I haven’t had personal experience with them. I did, however, make an inquiry with the seller about those very parts, ten years ago, and I found his responses to my questions evasive, so I didn’t buy from him.

No doubt we would all be delighted if we could buy quality parts at a fraction of the price that OE parts are selling for, especially those of us who use their cars on a daily basis, so please let us how many kilometres you get out of them. That may not matter as much to those who don’t travel long distances every year, but, safety issues aside, that’s what those who clock up a lot of mileage look at when trying to determine value.

I received the Mercedes style internal spring compressor, 2 days from order to my door, not bad service. The compressor is designed for 2 coils spring widths, it comes in a sturdy plastic blow mold case, with separate parts sections. I tried the compressor out today, I must say it works perfectly. It appears well made, the threads are even and uniform over the whole length of the shaft, the spring plates are substantial. Well worth the money. Regards Maurie.
