Knocking in front suspension

[JLUCQ]

Did you adjust your control arms or just turn the coil? Pretty sure thats what my popping sound is.

Not sure I didn't do the lift myself but I know they mentioned the isolator at the top of the coil can shift causing the bow. So I assume they just shifted it back.

Thank you everyone for the input. I finally brought it somewhere and we found out that is is metal particles in my differential fluid so I’m way over my head with this one. I appreciate everyone reaching out with all the suggestions. Comes to find out the noise is actually coming from the back even though it sounds like the front. When it rains it pours!

Unfortunately, a clunk can be caused b A LOT of different things on a Jeep. I chased one in my front-right for almost a year until my neighbor told me he thought it was coming from the right-rear. Sure enough, It turned out to the the RR CA-to-frame fastener was loose. (aka not anywhere near the 90 lb. ft. it should be torqued to.)

“Diagnostic fees” are B.S. in my opinion. I get that it takes time to figure out an issue sometimes, but if they do find something and you choose to get the repair done at the same place, they should wave the diagnostic fee, or at least take it off the cost of the repair. Now if you choose to go somewhere else, then yes, their time should be worth something - if they helped in any way. That said, We are the customer. We shouldn’t have to pay just to show up.

I think you should do your job for free too.

I respect your opinion, but disagree. I didn’t say mechanics services should be free. I just said that if you are going to pay someone to fix a problem with your vehicle, that figuring out what the problem is should be part of fixing it. People deserve to be paid reasonably for their time,yes. But you have to be practical - you can’t reasonably charge someone a $75 “diagnostic free” if all you did was plug the vehicle into a computer for five minutes and done. More complicated things maybe, but little stuff is what makes it unfair. And, conversely, if you only put time into identifying the issue and don’t get to fix it, then ok you should be paid for that, then. Not double-dip a customer on the same trip for little stuff. There’s been times where I’ve taken a vehicle into a mechanic knowing EXACTLY what was wrong and what I wanted done only to get the line, “We’ll charge the diagnostic fee regardless. If we get under your hood, we charge it.” To use your argument, I should get paid my salary for doing my job, and then charge my company an additional fee just for showing up to work if traffic was slower than normal that day. Nope.

There’s been times where I’ve taken a vehicle into a mechanic knowing EXACTLY what was wrong and what I wanted done only to get the line, “well we charge the diagnostic fee regardless. If we get under your hood, we charge it.” To use your argument, I should get paid my salary for doing my job, and then charge my company an additional fee just for showing up to work. Nope.

That’s exactly what happens when you get paid overtime. We can spend hours diagnosing a failure that takes an hour or less for component replacement. Nobody pays clock time diagnosis. Flat rate diagnosis keeps the doors open.

Then like I said, be practical and reasonable. If you diagnose the problem in 10 mins, don’t fee the customer. If it take hours to diagnose, then charge a reasonable rate for your time. I’m ok with that either way. Just not both.

Nobody is going to pay $1000 to repair a broken wire.

Right. They shouldn’t.

 

[mwilk012]

Right. They shouldn’t.

We work 8 hours installing parts and charge book time, nobody cries, 1000 dollars.
Spend 8 hours on your piece of junk pin testing every aspect of the electrical systems. Customer cries about 1 hour diagnosis fee.

I’m glad I stay busy enough to be able to choose my customers.

Finding the problem is not part of fixing it in terms of cost/charges. Do you expect your Dr. to find your problem for free, and then you can just pay him to “fix” it afterwards?

How do you justify my time having value if I don’t fix your car, but having no value if I do?

I don’t typically charge customers for what I do, I charge customers for what I know.

I know a lot. And it cost me a lot of money to gain that knowledge. Not to mention that my tools and diagnostic equipment cost more than your Jeep. And mine, and maybe even one more - combined. You’re damn right I’m gonna charge a diagnostic fee every time I plug in my scanner. I’m not working for free - especially for someone that expects me to

The JL is known for having a lot of metal in the diff fluid, moreso before first fluid change.
Did you have filings or actual chunks of steel?
What did they actually diagnose? Did they fix your issue?

Not sure how metal in the diff would cause a noise on left turns only.

Now that makes sense. Noise coming from the back axles is caused by the break down of the limited slip differential (LSD). This is a well known issue with non-Rubicon Jeeps. FCA has done nothing to resolve this.

The Rubicons have their own issues as well. The lockers stop working after a while because oil tends to leak on the locker's sensor and damage it.

https://www.jlwranglerforums.com/forum/threads/locker-position-sensor-potting-dana-44.59581/

FCA has done nothing to resolve this issue either.

The metal particles are actually pieces of the components that make up the limited slip differential.
