The 85SD needs a new rear windshield gasket.
The 85TD needs front windshield and rear tailgate windshield gaskets.


Do I dare use URO? Some of their parts are reported to fail almost immediately. Others (door seals for example) are reported to be good.


Anyone have specific experience with the glass. I'll be paying a shop so it's real dollars and not me just spending a couple hours trying to figure the process.

Save your money. They're garbage. After many frustrated, hope filled attempts, I gave up and purchased MB seals.

The windshields are big, expensive items and very important to keep leak free (especially the rear since the window surround is rust-prone from leaky gaskets). If it's a car you're keeping and MB seals are available, you're a fool to buy anything else, regardless of the cost difference. If you're paying a shop to do the work, you lost any savings if they have to pull the window and redo it because the aftermarket seal didn't fit.

FWIW, I used a Uro rear seal on a W123 before I knew any better. Ironically, I think it was the only Uro part I never had problems with.

Dkr.

I vowed several years ago I’d never again use a “Uro branded” anything after the very untimely failure of several parts I replaced with that god awful brand. Because of the very real consequences of a poorly fitting front or rear glass seal (moisture related electrical issues and leaks causing rust) I personally would never use anything but Mercedes factory gaskets.

• We sell about 250 of windshield seal 123 670 0139 annually with no defect returns or complaints in the last 12 months. Review on Pelican: "Good seal - This seal is a little different from the original style in that it doesn't have a rubber flange that goes over the chrome trim but it fit well and it's been great to drive my car again!"
• We sell about 200 of rear glass seal 123 670 0239 with 3 returned as "defective" in the last 12 months.
• For the (300?)SD, we sell about 40 of rear glass seal 126 678 0120 annually with none returned as "defective" in the last 12 months.

If anyone can provide any specific details on these seals could be improved, please PM us - we'd love to hear from you.

I've tried those on my 91 SD - save your money. The seal does not fit at all and don't even think about fitting the trim.....

Hi Don, we actually don't make a windshield seal for the 1991 350SD, any idea what other brand your seal could have been? We do make rear window seal 126 678 0420 for that car and sell about 30 annually with no complaints or returns, what specific issues did you encounter with it?

My URO radiator hoses are still doing fine 5 years on.

Bought at the same time as the trunk seal which I never used after the experience with the rear windshield seal. There's one on eBay right now.

Both seals came in URO parts plastic bags. The seal was attempted to be installed after a paint job, by a guy who does windwhields every day. I have no experience with that kind of work so I do not touch it. I had to move the car and due to that left the ill fitting seal in. Too many projects to fix it right now. Someday I hope to get to it.

^ Thanks, we'll have engineering compare that rear window seal to our OEM sample.

The sad thing is OEM seals from MB are NLA. If you can find OEM seals, they're probably NOS that's dry-rotted from sitting on a shelf for 30 years. I need to replace my rear seal on my 300SD at some point since the seal that's been on there about 20 years is showing some age and some rust needs repairing, and my options for an OE or OEM seal are slim to none.

I'm not knocking URO, but the one year return/complaint metrics don't tell us much about the durability of the product. You may have people who buy the URO seals and don't install them until over a year after they've purchased them, after the warranty period is over. The better question is 5-10 years later when the warranty period is over, how are they holding up? What is their long term durability like when compared to OEM seals?

FWIW ;

The original M-B replacement ones were very well made and came coated in paraffin to prevent degradation in storage....

I'd look on E-Bay.de for an N.O.S. one, I've used quite a few N.O.S. ones to very good effect .

Unfortunately for URO, no matter how hard they may be trying, it is very difficult to overcome the 'first impression' that lingers in everyone's mind about the quality of their product. Although name brand recognition is usually a desirable asset, URO might consider a new name to match their current consumer outreach and quality improvement efforts.
