View Full Version : Hilux Centre-bearings

Hey guys,

Did a bit of a search around but nothing I have found has really answered the question.

At the moment the centre-bearing in the Hilux keeps going, looks to be due to the lift-kit as the centre-bearing location has never been adjusted.

So I have an LN106 (1996) and this thread: http://www.4wdaction.com.au/forum/viewtopic.php?f=72&t=108778 has mentioned to basically get any bearing and fill it with Sikaflex 221.

This is the 3rd or 4th bearing due in nearly the same amount of time owning it, so I'm interested in a fix that doesn't mean I have to keep changing this over. Another thread I found mentioned using a single piece tail-shaft but the old boy doesn't believe this will work and thinks it will eventually fuck something up being a 4wd (transfer case of the like.)

Last post in this thread: http://www.4wdaction.com.au/forum/viewtopic.php?f=72&t=108778&start=15 seems to mention that they swapped out a tailshaft for the single piece from a 1KZ-TE Hilux, I'm assuming this is a turbo diesel model from 99 to 03/04 or somewhere around there, I think the Prado of similar era has the same engine?

Anyway, any recommendations? Or just slap in a cheap one and keep swapping them over as needed? Not sure on the cost of a genuine Toyota centre-bearing yet.


Cheers,

Paul

the 1KZ-TE was in later model surfs as well. my surf doesnt run a centre bearing at all. maybe do some research into rear tailshaft lengths between the surf/4runner and the LN106 hilux. heaps of parts are interchangable between the 2 so maybe you can change out the tailshaft you have with a surf one and never have the problem again.

I have an LN106 aswell, had the same problem too.. I wa slucky to get 2000km out of a centre bearing...

When I did the 5 litre conversion, I had the rear shaft shortened 3 inches, rebalanced, and fitted new unis to it..

Haven't had a problem since... The guy at the driveshaft joint said that any play in the unis or balance issues will flog the centre bearing out in no time because of the design of them..

A 1 piece shaft i spossible but would need to be 3-3.5" diameter because of the length of it.. which is just heavy and overkill for a little 2.8..

I've spoken to DSA and they've said getting a one piece through them may not be possible due to legalities, others have said to get one from a Hilux/Surf/Prado that ran that motor if the length fits (some have done this themselves) as it negates the issue altogether.

Others have said to just put spacers in to drop the height of the centre bearing and reduce the angle it sits at. For the meantime I'll be putting spacers in until I can locate/swap to a single piece driveshaft and pumping Sikaflex 221 into an old bearing's rubber to give that a shot. The car barely gets driven these days now that I ride into work and back.

Had the same problem in my 97 tf rodeo 2.8l diesel 4x4, after i put a lift in (2"). I just put the new center bearing on, looked at where it wanted to sit and re drilled the holes. Never had a problem again after that. Don't know the hilux setups but I'm sure you could move or re weld the mounting point back more.

Have you got your shaft phased properly? If someone has pulled the slip joint out and put it back in a different spot you will destroy bearings.

If it's raised you could also space your gearbox mount down to make it less of an angle.
Need to get the angle of motor/box the same as your diff pinion angle and it should be fine.

Yeah that is what the spacer with essentially do, make it possible to move the centre-bearing down.

No idea on this one, will have to get this checked by the looks to be sure. Some muppet previously put the shaft in wrong and didn't align it properly (by the looks the shaft has teeth that vary) so it caused a bunch of vibration and ate the rubber of the center bearing. We put it back in properly but it has obviously eaten out another bearing, though it took longer this time.

I will have to check this - not sure how the previous owner put it together to be honest.
