Idler bushing options

Anybody know of something with delrin or poly? Be nice to try and tighten this area up.
 
The only option I have ever been aware of for idler arm bushings, is the factory kit. This is one of those parts where you DO NOT want to go aftermarket. I have never heard of any poly or delrin busings for the E500E idler arm.
 
I might add, this can be a pita job pretty fast. My impact gun could not get the nut to break. I ended up with a dremel and several cutting disks. I would hate to go Febi on this one after the joy of getting it off, then the joy of getting the linkage back together in the tight space.

Same here. The factory new bushings are FIRM. I don't know if replacing with poly would make any difference.

Are you referring to something else besides the idler arm...?

Along these same lines, are the idler arm bushings difficult to replace on the W124? I don't think I've ever done a set on a W124. I know that on other models there can be issues with clearance for the bolt.

Yeah, it's generally a PITA, as the exhaust is in the way. IIRC, @nocfn had a trick to make it easier. These bushings last a LONG time on the M119 cars though, they are beefy. Spec is 0.5mm play so measure first before replacing.

The OE kit is $184 MSRP now. Back in 2005, this was only $69 list, $41 dealer cost.

My brother used to work for global West suspension in San Bernardino.
They use delrin bushings for lots of different applications and we're custom machined.

I don't know if they would machine custom ones for you or not.

But give the a shout!

Yeah, they're not fun on some of the other chassis' as well, I just don't recall ever having done a set on a W124. I'll check mine but I"m pretty sure they're within spec based on having looked at them previously.

I saw the price on the OE kit recently when I was putting together a potential deferred maintenance parts list. Ouch. I wouldn't use anything but OE on a part like this anyway.

Thank you!

It is well documented on this forum about the quality of cheap Chinese-made aftermarket parts.

How bad could it be?

Pretty damned bad.

I really wish we could put these purveyors of crap out of business.
In a lot of cases it's getting to the point that this crap is the only option being sold. My wife just ran the car through the car wash with the radio on. Looking at my options, the antennae is NLA and it seems that Autohaus and RMeuropean are selling the same Uro crap. I found a factory Hirshmann on Ebay for $90. As easy as it is to change the mast, I just couldn't put a Uro part on my car.
 
Are you sure that RM is selling Üro crap? The @gsxr told me previously that he prefers/shops there because it is largely a junk-free zone. Say it isn’t so.
 
You just KNOW that when an ersatz part only costs 10% of what the "real" part costs, that it's going to be utter garbage. A 90% lower price than stock is at a level that even URO doesn't get to all that often.

And you think about it -- RM Yurropean is making a profit selling this antenna at $11.00, which means they probably purchased it at around 50% of that price.

I guess all of the major aftermarket vendors are carrying this blight on humanity these days. Sad.

It would be interesting to purchase one of these ersatz antenna masts, and see how long it lasts in comparison to a proper one. But like you, I just ..... can't ..... bring ..... myself ..... to put URO parts on my cars.
 
Actually, before I was awake to Uro's lack of quality, I think I actually installed a mast on my 400E and it broke post haste. Part of it got jammed in the motor.

RME is largely a junk-free zone, but it's not completely junk-free. The Hirschmann mast has been NLA for a while now, and NOS ones have been pushing $100 if you can find them.

<flame suit on> Think I've mentioned this before, but when the E420 needed a mast, I couldn't justify $100 on it... went with the Üro mast and, shockingly, it's been fine for years. Granted, this is about the only Üro part that I'd want to use. The 036's still get Hirschmann. Now, if Üro ever starts making 036 Euro headights for like $150, a lot of folks might re-evaluate their unconscious bias! </flame suit>

Perhaps MB will commission URO to make a production run of 500E Euro headlights. We will let you be the guinea pig. I'm sure the silver reflective material would fall off of the inside of the lamps within 100 miles, and the glass would be cracked by the impact of a house-fly getting smashed against the lens at speed.
 
If MB did get URO to make a production run of 500E euro headlights they would still be URO junk
but I bet they would still be MB prices
Some genuine parts are made in China now, But they aint no cheaper

confession.jpg

Since we're giving confession here...

I, too, have purchased a Üro antenna mast for my 420E. I'm not going to drop $100+ for a mast on a $1500 car. I figured I would roll the dice and see how it worked, and it does. The fit and finish isn't great, but it works better than the old mast that is still, after soaking with Kroil for over a week, immovable in the center section.

I also once bought a Üro grille for a W123. It was an absolute POS. Fit and finish were poor, I had to file the opening for the hood ornament base for it to fit properly, and the angle at which the grille shell was formed (inverted "V" shape) was incorrect, causing it to not mate with the edges of the hood properly.

Never made it onto the car. I took the plastic inner part out to try in an OE shell in the future and tossed the shell in the trash.

Lesson learned.

It seems that there is a new national spirit in the US of contrition, and admitting one's broken-ness, failings, and need to repent and grovel for who they are and were born as. So it is good to see that even among the most steadfast and resolute of us, there are closet URO lovers.

@LWB250, it seems your W123 grill experience mirrors pretty much identically that of the W124 Wizard of Western Australia (WWWA), who on YouTube goes by the handle of "MMWA". This guy is an absolute GENIUS with 124s. Someday I really do hope to meet him.

Check out his video on the topic, which I've posted below. His other videos will provide hours of information and entertainment. He is nearing the end of a years-long nut and bolt restoration of a CIS-E powered M104 W124 sedan.

Already seen and commented on a while ago. Validation for my findings. I'm not a Üro lover in any sense of the word. I made one-off decisions based purely on economics for both purchases. The mast I'm more or less happy with considering the alternatives, much as the @gsxr. The grille was totally on me, and ended up in a loss of roughly $60. I rolled the dice and crapped out.

My expectations were very low. They were exceeded.

I have a URO windshield seal in my 77 240D and it’s been holding up perfectly fine over the past 10 years since I had it installed. At the time it was the only one available for the W123 so I didn’t exactly have any alternative but I’ve been pleasantly shocked by how well it’s actually held up. In full disclosure the car lives under a cover in the garage.

On the original topic of the idler bushing it’s not a terribly difficult job. I’ve done it on both a M119 and M103 powered W124 and it’s far easier on the M103. There is a great how to here on the forum for the job.

I've tried to invite MMWA to this board by commenting on his YouTube posts, but to no avail. He did "like" a link once to a thread on this forum I posted to his inquiry
 
FYI.......Hedgehog Tuning and Motorsport came out with the poly idler bushings on March 7 on their Facebook page if anyone is still interested.
