Drive Line Thunk Solved?

[2001LC]

If a mall cruiser you can easily go 60k

I suppose double factory miles provided one keeps re-setting breakaway preload to keep tight.

Bearings loosen ~5K miles after service so be a good first re-set point, additional re-set at 30K miles or sooner. Keeping wheel bearing tight, protect front drive shaft axle splines & knuckle, along with hub flange teeth.

Hard to beat your factory's, I protect them.

Are you buying a new axle and flange?

Are you buying a new axle and flange?

If you're asking me, No, that's the point of frequent wheel bearing service.

If during an inspection I get a hard N to D or N to R clunk, I assume at minimum I'll be replacing axle hub flange. But a new OEM axle & flange will reduce the N to D clunk the most.

The propeller shaft clunk is different (during braking & acceleration), which lubing slip yokes often corrects. That's provided grease passes seal during lubing, otherwise more in-depth cleaning of yokes is helpfully. The last step if all else fails is drilling a small hole in backing plate of yoke to act as pressure relief valve.

Both these are general symptoms and cures. I'm sure you've seen exception as I have, and some clunk with mileage is certainly acceptable. But none of this is news to you @PabloCruise, as you've a good handle on the 100 series.

Yes, both drive flang and half shaft were replaced and amazingly the thunk has disappeared. Life is good again.

Were a the grease pins located for slip yokes has anyone got a diagram or pictures

In 98-02 rear Slide Yoke is near read differential. 03-07 it's near the transfer case as depicted below. I may be off on what years this change was made.

Thankyou. I have a 2001 so I guess may be as you said rear diff.
