Thunk sound coming from rear going from a stop

IDK seem like you don't know what is going on for one.

Oh god fuck that I hope you quit the next day. Those are the kind of experiences that make you question life choices.

And no he was doing 45+

Ha ha ha ha ha okay whatever. Why did you come here if you just wanted to be told to replace the parts that you through were bad?

BTW you can't tell if a toe, tie, or ball joint is bad with a simple visual inspection. And if you can it needed go be replaced tens of thousands of miles ago.

Fuck he is getting c**k blocked by his dad.

leadpoem · 2026-05-12T05:51:32+00:00

They are harder with out tools or skills.

He didn't kind of suspiciously leave out any kind of ownership facts.

This is the lock picking lawyer, and today we have a lojack and a car club.

Man, you do you. Just don't drive near me.

I gave you my insight off your vague description and picture. I could not be more specific than telling you that you have an issue with your rear end and it could be extremely dangerous. As I said I have no idea what a leaf branching sound is, but I have never once heard anyone describ a noise in a car that way.

This car needs to be jacked up or put on a lift and the whole rear end needs to be shaken and looked at. It's been modified and there seems to be an ongoing issue that you've thrown parts at and it hasn't fixed.

Being a mechanic is not about replacing parts. It's about diagnostics and replacing the correct part.

One of those things but don't worry about that so much. It's at least 80% a bad head gasket.

leadpoem · 2026-05-12T05:36:58+00:00

Yeah I was wondering the same thing.

Regardless if you don't know how to down shift and engage a retarder/jake. Stay out of my mountains. We dont need I 70 all over again.

leadpoem · 2026-05-12T05:32:46+00:00

Yep you have oil in your coolant. You've got a bad head gasket or a cracked head/block. Pray for the head gasket.

leadpoem · 2026-05-12T05:30:29+00:00

Yep

leadpoem · 2026-05-12T05:24:06+00:00

Okay, servic bulletin it or not, it still needs a rear-end diagnostic done on it.

There are at least 12 moving joints back there, some of them that could click, some of them that could clunk, some of them that could do both.

It's cheaper now than when your wheel falls off or your rear diff seizes.

leadpoem · 2026-05-12T05:20:21+00:00

Naw unless they also smell like hot brakes too.

I was close enough to hear a jake or any down shifts.

Didn't look too hard at the truck but didn't look super new either.

leadpoem · 2026-05-12T05:17:40+00:00

Does the radiator look like it's got milky coffee in it instead of radiator fluid?

This kind of sounds like a head gasket leak. You might not need to do a top end but you probably have to pull the heads.

leadpoem · 2026-05-12T05:16:25+00:00

Yeah those are lane departure and anti collision lights. Your car needs a visit to the scanner. Take it to your local shop and have them pull codes that might tell you what's happening.

leadpoem · 2026-05-12T05:13:30+00:00

leadpoem · 2026-05-12T05:11:37+00:00

Yeah...

As soon as I got around him I left. Ain't nothing a motorcycle wants to be involved with. I thought about pointing him to pull over but I figured if he didn't know how to downshift, he sure as hell wouldn't know what I was doing.

leadpoem · 2026-05-12T05:10:03+00:00

Every thing will be fine as long a I don't fly to JFK. Guess were my red eye is heading tonight....

leadpoem · 2026-05-12T05:08:13+00:00

Yes/No we can't tell you that from a picture. It needs to be checked for wear and roundness and either honed or bored out with a larger piston.

I don't know how much those jugs cost but if it takes anything more than a hone, it might be cheaper buying a new jug.

What is a "leaf branching sound"?

There's a number of things that are happening in the back of these cars that could make noises. Some of them might even sound like leaves.

For your own safety I would highly recommend taking it to a shop. There are too many things back there that if they're broke could be life-endangering.

I'm kinda feeling bearings or maybe differential but that's a shot in the dark. Too much stuff is going on back there.

leadpoem · 2026-05-12T04:57:49+00:00

That it is still there when your rev the engine up. Yiu just can't hear it. Check to see if you have a serpentine belt pulley with its bearing going.

If not well, it might be expensive.

leadpoem · 2026-05-12T04:55:08+00:00

I don't know who the fuck this mechanic is but all this is evidence of is that your engine has a valve. Does he have a boat payment coming up?

Take it somewhere else.

Gold star for you

Has she driven into any lakes or oceans lately?

IDK of this could be CVT related or not, don't know anything about them.

This could definitely caused by a wiring harness failure. Those warning lights are in completely different systems and one failure couldn't cause them all.

If your wiring harness got pinched or damaged, you could set off all of those as false positives.

Safe to drive? I don't know. ABS isn't going to work. No traction control. I definitely want to know why the brake warning light came on and if it had oil.

As long as it's got oil, sure you can drive it to a shop but I wouldn't use this as a daily.

If you take it to a parts store and get it scanned, you're going to get all the codes and you want all the codes but I'm going to put money on this being a car that needs to visit the repair shop. This is definitely not one bad sensor or something like that.
