We're in! '99 LX - new to us! (1 Viewer)

And, I hear a "squeak-squeak" noise when the wife backs out of the garage.
Sounds like it might be u-joints?
Time to see if my ancient grease gun will still work, so if those joints will be happy w/ a little lube...

"squeak-squeak" is very likely U-Joint or brake pad rubbing.

My money would be on a U-Joint or two.

I was going to try the grease gun on u-joints to see what that does. Except my grease cartridge was empty
Or do you think I am beyond that if they are squeaking?
When I try to twist the driveshafts, I cannot detect any play...

They might still be serviceable if it hasn't been going on for too long (and the squeak is indeed a U-joint). But unless you remove the driveshaft it is hard to tell what kind of wear they have since usually you can't move them because of pressure between the Tcase and the differential.

But U-joints can be quite long lived (if greased faithfully). I have the original U-joints in both by 80 series (with 332K miles on it) and my 100 series (256K miles). And both exhibit no issues.

Thanks for the reply!
Off to the local NAPA to get a cartridge for the grease gun. My memory of that thing is that it was a PITA to use.
Which probably means that the 40 and Pig are overdue for a visit with the grease gun as well.

Ideally there should be very little pressure between t-case and diff flange, eh?
I might crack the grease nipple on the driveshafts loose to make sure there isn't a lot of pressure from previous lubing.

Axial direction yes. IF you overfill the driveshaft and the seal doesn't allow grease to pass you can unwittingly apply a LOT of pressure against the Tcase. The driveshaft as you know is designed to lengthen and shorten under suspension travel.

The pressure I refereed to earlier was with respect to rotational pressure Tcase against Differential. Often times when a vehicle is parked there is pressure on the driveshaft which doesn't allow you to move it and assess the condition of the U-joints. So in error....it is assumed they are tight.

Got it, so maybe try things with the tranny or t-case in N...

Yep.

 

[PabloCruise]

I lubed the u-joints and slip yokes on F and R shafts.
She still squeaks when under power in R.
Sometimes this is no fun.

 

[PabloCruise]

Sounds like the squeak is coming from the rear u-joint of the rear driveshaft.

Am I correct that we can drive our 100s/470s on the front shaft only if you lock the CDL?

Thinking I will pull the rear shaft and sent out to the local driveline shop for u-joints and see what they can do about the splines...

 

[PabloCruise]

I gathered up all the parts to do front and rear sway bar links.
I didn't see any good threads that spelled out the Toyota p/n's for doing this job.
I think I will start a separate thread so folks can find it easier than if it were buried in here.

I take it back, there are a few good threads for replacing sway bar links and P/Ns:

When & how to replace stabilizer bar, bushings, cushions & links (AKA sway bar)

Would you say I waited to long to change my bushings! But link breaking is not the only reason why I say to long. I found not only did Link rust through, but I also removed a ~1/16" of rust off top & bottom of stabilizer bar recess that the cushions sets in. I then found the stabilizer bar...

Parts list to refurb your Sway Bars

As part of my ongoing maintenance and refurbishment of my 2000 Land Cruiser I'm freshening up the sway bar bushings and mounts. This list is for anti-roll bars only. I will be doing the control arm bushings as well in a separate list. I'm using all OEM parts. Note: Some of the lock nuts have...

So I don't think there is any need for a new thread.

It occurred to me that the above prices came from partsouq, and may not reflect current list prices at the dealer parts counter.
Sure enough! Here is the updated grid with pricing from mid-April of '22:

Economics seem to point to replace the rear shaft:

Rear Driveshaft - Rebuild or Replace?

The rear u-joint on the rear shaft on our LX makes a squeak-squeak noise when the :princess: backs out of the garage. I thought about sending it out to the local driveline repair shop, but then I heard they will use Spicer joints vs. Toyota to rebuild. Then I called our friendly neighborhood...

Sway bar end links are done!
That was probably one of the easy tasks on the Flexus!
I hit the threads with some Kroil a few times before the job and this job is in the bag.

You can see how mashed the bushings were...

SHAFT!!!

Did you add some grease?

At the parts counter they said the assembly was greased from the factory.
What are your thoughts?
