hi all,i removed the gearbox from my hilux to replace the rear main and clutch and upon removing it noticed the the spigot bearing had packed it in and there was nothing left of it,the input shaft on the gearbox has some play in it and the front bearing on it has lost about four of the ball bearings,it will be going to the gearbox bloke tomorrow but any idea on how much i will be looking at paying to have the front bearing replaced?
cheers

I know its not terribly relevant, but I just had 2 gearboxes combined into one (as in, I had a spare box, condition unknown, and had to fix a blown fifth and output shaft) and to tear down 2 boxes and rebuild one with a combination of parts, and throw a bearing kit through it was 350 labour, plus 250 for the kit....
and I couldn't get my damm spigot bearing out for ages, dog of a job...!
maybe that helps... or not

2 ways to remove spigot Ive used,
1. Bearing race type
Soak in penetrene, pull out using an internal puller with a hook leg
2. Solid spigot.
Fill behind with thick grease.
Make up a neat fir rod to fit thru hole into grease.
Bash with big hammer hoping it hydralics the bush out.
(USE safety goggles !!!)

yeah the grease method ended up being the way we used. We had a spare input shaft from the nice man that fixed the gearbox, which we used to align the clutch, and it has the litlle nipple in the end that sits through the bearing. We packed out the hole with grease, and started bashing, more grease, more bashing and it eventually started to move.
In hindsight, we'd use a piece of dowel that was almost a perfect fit and it would have come out in a few minutes, not the better part of an hour.... :( We had grease blowing back past the thing we were banging in, meaning that the hydraulic principle was rooted... But we perseverevd and got it out. That, and we didn't have any dowel...
Its simple and worth doing. Go the dowel and it will pop out easy. Make sure you put the grease in with a gun tho, fingers trap the air in there which compresses, unlike the grease.
