Is there a slick way to clean old grease from bearings and regrease or is it still a toothbrush/ simple green thing?

If you use grease you need to get all the old grease off so it doesn't foul the new grease causing it to do one of two things: harden or liquify, thereby losing it's lubrication value.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

So I'm giving it a go. but the upload for photos is down. Any guesses in the meantime? 2000 C4. Now in my care.

POST 2Original post

Bump stops and Top Mounts possible for "Clunk". Wheel bearing for "grind"? More details (or better yet a video) would help.

POST 3Original post

Its a C4 so maybe even axles are grinding possibilities...

POST 4Original post

Sway bar drop links and bushings for the clunk. At least that fixed it on my C2.

Yes, the upload fx is on the fritz.

POST 7 / ORIGINAL POSTEROriginal post

This might be part of the problem. ..

POST 8 / ORIGINAL POSTEROriginal post

Pop quiz: What kind of springs are these?

POST 10 / ORIGINAL POSTEROriginal post

Why are there ball bearings at the top of the strut?

POST 11Original post

Is the car lowered? Maybe H&R Sport springs based on google search. https://www.vividracing.com/sport-sp...04-p-1704.html

POST 12Original post

The bearings at the top of the front struts allow them to twist when the suspension is moving. The rear doesn�t have that. You need to keep contaminants out of that top mount bearing.

POST 13 / ORIGINAL POSTEROriginal post

Quotes source post: 15563013

Yes, agreed. I don't think C2 struts have them. What's the diff?

POST 14 / ORIGINAL POSTEROriginal post

Quotes source post: 15562943

Hmmm. Might be right. I can't read the numbers. Anyway, you are at least partially right and get credit. The other part of the answer to what kind of spring it is would be? Broken. I'm looking at options. I guess that's not unheard of. Is it common?

POST 15 / ORIGINAL POSTEROriginal post

What's the story on top mount options? Time to replace them, 19 years is over due. OEM vs. aftermarket vs pillow ball?

POST 16Original post

Quotes source post: 15563285

C2 struts have them too. The whole strut housing turns when the front wheels turn. In fact, the strut is the pivot axis around which the steering angle rotates. If the top mounts didn�t have bearings, because of the weight of the car, the springs would cause resistance against the wheels turning to steer, especially while cornering.

Thanks Joey. Is there a slick way to clean old grease from bearings and regrease or is it still a toothbrush/ simple green thing?

POST 18Original post

Quotes source post: 15563341

I want to put a set of adjustable Elephant Racing mounts in mine. They are somewhat expensive however.

POST 19 / ORIGINAL POSTEROriginal post

So, how bad are after market rubber top mounts vs. OEM? Which ones are holding up?

POST 20 / ORIGINAL POSTEROriginal post

ok, maybe this is a problem. my worst clunking was, not surprisingly, over bumps. broked

POST 21 / ORIGINAL POSTEROriginal post

Tooth brush sacrificed. Simple green because I don't like breathing volatile organic brain melting vapors.

POST 24 / ORIGINAL POSTEROriginal post

Does H&R replace broken springs?

POST 25 / ORIGINAL POSTEROriginal post

Ok, got a day off. I've got replacement springs, so I'm ready to re assemble the spring/strut. I will also be replacing the 18 year old top strut mounts with new ones before they fail. It looks like the top bearing gets water exposure from below in the wheel well. Is this a marine grease application? Or just white lithium bearing grease?

POST 26Original post

Those aren't H&R sport springs. They look stock. Look up the paint markings - looks like two white dots, but can't be sure - it looks like some might be scraped off...

POST 27Original post

I greased my new strut mount bearings with silicone grease. No moisture absorbance. Quiet now for years. Weird to see the broken spring...must have been one helluva pothole!

POST 29 / ORIGINAL POSTEROriginal post

Quotes source post: 15615453

Thanks, it really doesn't need bearing grease per se since it probably won't see even a full revolution but once in a blue moon but the race looks like it could be vulnerable to water and contamination along the inner ring. What does the factory do here?

POST 30Original post

Quotes source post: 15563705

Does the C2 bearing plate come apart as well? getting ready to do my struts as well just buying parts each payday if I can save them I can do them sooner

POST 31 / ORIGINAL POSTEROriginal post

Quotes source post: 15617169

I can't say. The diagrams don't show this one as multipiece either so it's possible. I would not be surprised. I'm going to use an anhydrous calcium based grease. It is a marine grease that has better qualities for this application than a generic lithium grease, primarily better water resistance, as this bearing is at the top of the wheel well and will see splashing. If you use grease you need to get all the old grease off so it doesn't foul the new grease causing it to do one of two things: harden or liquify, thereby losing it's lubrication value. Think of the times you have seen grease do one or the other.

POST 32 / ORIGINAL POSTEROriginal post

Does this look like H&R? Maybe the spring had a pit that corroded and was weak?

POST 33 / ORIGINAL POSTEROriginal post

This is in and I got to sneak out between snow storms this afternoon... ah, now it's downright driveable. Gotta do the other side. Should be quick.

POST 34Original post

That photo above does seem to show the "H" in the H&R logo (with a series of #'s after it) - I didn't catch that in the original photo... What are the new springs? Eibach maybe? I think I have read thread about them failing ( definitely the sway bars, but not sure about the springs - they seem to be somwhat softer than the H&R's...)
