I had the Raider towed to a driveline shop. They test drove it and the conclusion: The noise is the transmission, possibly no / low oil and the bearings are shot/ poor. This based purely on a test drive and they also feel the backlash etc is accceptable.
I replaced the tcase fluid 5000 miles ago. No problems prior to getting the diff done. No noticable leaks from the rear driveshaft seal prior to this weekend. AS of this writing the drivetrain place hasn't checked the oil tranny oil level.

Mechanic #1: "We did not lose any tranny fluid when pulling out your driveshaft, the shaft is above the sump, and therefor we could not have lost all your tranny ( edit tcase) fluid. Possibly the extra "stress" of having an LSD rear has compounded what was a very slight whine prior to installing the LSD. ( I say again, I have never heard a whine before )

i AM SO PISSED OFF i'M SHAKING

Option 1 ) Be a sucker, tell the tanny place to fix whatever is wrong , spend an estimated 800$ or whatever and deal with it.

OPtion 2 )Tell mechanic # 1 that I feel the stress idea is BS and that i will authorize the drivetrain shop to do the work and he will be billed for it ( sued ) as I feel I should get my truck back in the form it was delivered.

Option3) Tow ( my expense ) back to shop 1. Pay to have the open slip re-installed.( 200$ ) If the noise goes away, then accept his explanation. If the noise is still there, refuse to take the truck back until the truck is normal again, at no expense to me.


Suggestions anyone??

Update #2

Tranny shop pulled the driveshaft on a hunch- VOILA no noise as they then went through the gears. So OOPs, " we were wrong, doesn't look like it's the tranny after all" but the LSD. ( Is it normal right about now to feel that every shop is completley ....incompetant ?? <img src="/forums/images/graemlins/shame.gif" alt="" /> )

He said for around 300$ he'll take the whole LSD apart and see what's wrong. OK <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

Maybe it got dropped hard in shipping, maybe things dried out while waiting to be installed. Anyway, Come <img src="/forums/images/graemlins/evil.gif" alt="" /> or high water, I'm gonna have an LSD.

I am not up to date on your other thread, so maybe you can bring us up to speed.

There seemed to be confusion on whether they installed the third member.

Or just the differential.

If they installed the 3rd member that means you should have your other one in your possession, complete and ready to go. If you have a "decent" collection of hand tool with metric sizes, and "some" mechanical ability you should be able to put your original third member by yourself.

This would confirm if it is the third member or not.

They are correct just pulling the drive shaft will not cause the tranny to lose any of fluid. Unless it was overfilled it usually wont lose any gear oileither . However if the truck is driven with the drive shaft out, the yoke is not there to hold the gear oil in, and you will lose a good deal of it.

IF, that is an if, if the fluid was low, and they aren't bullshitting you, it would be hard to prove that they did it. This is a manual or an automatic. I am guessing a manual.

There is no extra stress from the LSD. The LSD in a straight line will behave the same way any other diff would, open, locked, welded. In a straight line they all do the same exact thing.

Make sure you document everything that goes on on paper. You might have to take them to small claims court, and you dont want it to be a she said he said thing.

4x4,

edit: glad to hear it's not the tranny...

Just a note:

I had VERY BAD experiences with a transmission shop called 'The Transmission Depot'. They have the slogan "Honesty is our policy" and it couldn't be further from the truth...from my extensive experiences...VERY LONG STORY THERE.

Anyway, I just thought I'd let you know of my experiences with them and offer a warning.

BTW, 'The Transmission Depot' franchise that I got hosed by went out of business (no wonder) but I think there's still one in the west end close to Yorkdale.

Up to speed? Sure.

The LSD version of this was installed by Shop1:
Diff

It sounded terrible. Towed to shop# 2.
Shop#2 diagnoses as Tranny problem.
Shop# 1 Stated it wasn't caused by anything they did. They said possibly "stress" caused by the LSD vs an open diff. ( 5 speed manual ).
Shop 2 Takes out rear driveshaft and test drives- no noise. " Oh, guess it isn't the tranny" <img src="/forums/images/graemlins/rolleyes.gif" alt="" />
So something must have got damaged in shipping and the LSD needs to be re-set up.
Shop #2 suggests re-doing bearings while they are at it.
So, $300 Labour, 150$ in bearing parts plus the original R&R of 400$ gets me ( hopefully ) a fully functional LSD.

PS: Thanks Fuzz, I'm dealing with Tranny shop #2 in Pickering. Nice guys, they mis-diagnosed but I'm feeling really forgiving - and they caught their mistake.
I'd ( so far ) recommend them. PM if you need the name.

The driveshaft and transmission oil have NOTHING to do with each other. You will not lose a drop of tranny fluid with the driveshaft out, whether you drive it or not. However, you can lose transfer case oil with the driveshaft out, but never transmission fluid.
If you get tranny fluid out the back of your t-case....then you have serious problems!

Just for a try, rotate your driveshaft 180* and put it back on. There is a very slight possibility that the driveshaft is just out of balance, and rotating it might help some. Like I said, it a long shot, but heck, it only takes 5 minutes to find out.

Thanks for clarifying my mindless dribble. I was talking about gear oil being lost from the tcase, not the tranny.

I have been up all week doing finals, and havent been sleeping at all.

Did you ever check the oil level in the rear diff after you starter hearing problems, or did you take it back the let them "check it".

I am seriously doubting you can abuse a 3rd member enough in shiping to cause bearing damadge, or any damadge period. You can bang your flange of the diff on a rock on the trail and not cause any damadge, the shiping guys would have to be doing some serious beatings to replicate even that much abuse.

The driveshaft wouldnt result in this problem. Vibrations sure, not bearing noise.

I cant get to your imagestation pictures. They want me to sign in, forget that place.

Did they check if you driveshaft was balanced?

No, I didn't check after I picked up the vehicle originally. I had supplied 2 quarts, and they stated thay had opened a third to top it off.

Ya, I meant tcase fluid too,
Ya, image station sucks. Sorry.

Balanced drive shaft? I don't know. Wouldnt that have caused noise/ vibration with the open diff as well prior to the installation?

Well, I don't know. Somewhere between sending and installation something got broke. Maybe the shippers dropped it, maybe Mechanic # 1 dropped it on the floor and decided to install anyway, maybe something got dried out inside while waiting. Who knows. I'll find out monday after the whole unit is put in with new pinion bearings and carrier bearings.

A hard drop could be your problem, I cant honestly claim that there is no way you could damage it by dropping it or mishandling it.

Drying out isn't an issue, or every time you let the car sit you would be replacing rear ends. The pinion bearings and some of the other parts inside that diff aren't constantly submerged in oil. Instead they get lubricated when the internals are moving.

I cant say exactly how the oil gets slung around inside the monty diff, but usually the ring slings oil onto the pinion bearings and so on. So as soon as you got it moving again, it would be receiving all the oil it needs.

That is assuming of course that the shop put oil back in the diff after they were done with it.
