Just replacing inner and outer seals on hubs after a bit of water got into bearings, and noticed when hub is completely stripped off and outer cv shaft bare that right hand shaft had a thin (about 1 mm) washer or shim on the innermost face of the shaft where it comes into contact with hub and needle roller bearing. About 6-7cm in diameter. But no such washer on left side CV shaft. Wondered if it is someone's later addition to compensate for a bit of wear, or is it standard setup to have the washers on both sides - this is on an 88 Bighorn with Aisin manual hubs.
Thoughts welcome - Mike.

Come to think of it I did see an exploded diagram of cv and hub setup recently and I don't recall seeing a washer/spacer on innermost face of cv shaft. Must have been someone's addition.

Its a thrust washer and has 2 slots for grease. It is needed to get the endfloat right (almost none) at the circlip. One of mine was almost worn away and without it the cv would move in and out pumping water into your nice new bearings. Its ok to put together without it but stay away from water till you replace it.

Yes it does have a couple of tiny grooves in it - is it only meant to be about 1mm thick?

If you have trouble finding a replacement one Mike, i can machine one up for you. I just need dimensions and material.

Not sure on thickness but think its more than 1mm. The only one I can get at is paper thin so no help.

Thanks guys - went down to Isuzu dealer with stuffed washer and he tells me they are listed on diagram simply as washers - available ex Wgtn for about $5.00 each. Found a newish one at a wrecker and they are 1-2mms thick with distinct grease grooves on either face and the perimeter edge is bevelled to fit somewhere. Wrecker told me they actually fit inside the innermost seal - not the seal we fit when doing bearings. Will try to buy them and attempt fitting. Obviously however they are essential for water protection and keeping grease in place. Thoughts welcome
Mike.

They will pass through the seal in question as they are smaller but if this seal is more than 3 years old replace it as well. Not sure which way round it goes but it will be obvious. The seal is accessable from the rear of the hub assembly and is an Isuzu only part not too bad in cost. Check the needle roller at the same time Its also not expensive but has to be driven out from the front of the hub which is a lot easier with the wheel bearing out.

The thrust washer goes in the stationay hub as Geeves indicates, it bears against the rotating CV shaft. The oil/grease grooves should bear onto the moving surface. That is the groves to the CV shaft. If you need a hand Mike maybe we should have another Garage session. It's a common thing these front end bearings.

Could be a useful idea James. I wasn't aware of the washer - mainly because my left hub didn't have one. Will put a new one in the already disassembled right side tomorrow but I can leave off stripping left side and putting new washer in until a garage night - so long as its not too far away. The washers are pretty important items esp if doing plenty of river work in Canterbury, and it will be good to show one fitted one into place for other guys. Could save alot of mystery wheel bearing failures for all.
Am eyeballing the phenomenal snow in the mountains - though its all round my house today too - and plan to be going up there any weekend now. How would a Wednesday night about 6.30-7.00 suit you? Next Wednesday 21st is a possibility and would suit well. I can also do a fortnight later Wednesday 5 July. Whatever suits - will be easy to gather 5-6 club stalwarts around for a session. Give me a buzz if you like 3224570 and we could see what works
Mike.

Ok we will arange something then. I am not well placed this week as I'm trying to meet a deadline this week for new requirements from Land Transport New Zealand for rail licence holders. About 300 pages of paperwork there. Why isn't the same standards applied to road operators when you compare the safety records?.... anyway... Next week should be good, but we might need a differant venue as things are a bit full at my place at the moment. Garage access is nill and the drive is blocked with one of the flatmates various Land Rover projects. Engines and chassiss everywhere.... at their best I suppose.... in bits. :-O

i hate to dig up an old thread, but im having wheelbearing problems at the moment and im prety sure i dont have these washers in both sides.
are these washers that go behind the circlip that holds the cv shaft to the locking hub? were could i get some or could i just use a normal washer with the same dimentions?
im not sure if nelson has an isuzu dealer?

Holden dealer can get the parts. This washer sits inside the seal in the back of the hub assembly You have to remove the cv to get at it. Its about 60mm in diameter with 2 grooves.
If your haveing trouble with water getting into your weel bearing it could be worth taking the whole stub axle assembly of and checking the seal and needle bearing in the back of it. The seal is x holden only but the bearing can be got elswhere if you have the number but its not expensive from holden and they can look it up.

That seal goes in the hub as normal. There is anouther seal that could be your problem. How often are you haveing to do bearings. If theres water in there it may pay to check the other seal but it means popping ball joints to get at it.
Ive sent a diagram of the earlier model to your hotmail to give you an idea
