GU wheel bearings

It sounds as tho it was was too tight. The recommended method and the one I use is to check with a dial guage and tighten just until there is no movement. No tighter.

I take it up quite tight at first to seat everything. Then back it off. Then with dial guage fitted, back it off and bring it up again until no movement. If a hole doesn't match then back off slightly. Recheck play once all fitted and give the wheel a good shake every few days for a while, as sometimes you think it is up tight and it isn't. so it pays to check

My gu has 118,000km, going to cape in about 4 months should I be getting my wheel bearings done.

Hi Austravel
I own 3 Toyota's and do most off my own maitainence including wheel bearings, I re grease mine 40.000 km with out fail replace if necessary.
One thing I have learned over the years is how tight they should be,The rear stub axel on a toyota has marks on the edge that show were the locating screw goes on the axel nut .
I have all ways tightened the locator hole on the nut firm past the mark and then loosen back to the nearest mark ,Im talking mm if Nissan doesn't have these marks I suggest tighten firm back off 5-7mm once its all back together tack for a good drive 40-50 km put your hand on the hub if you can hold your hand on the hub for 30 seconds you've done it right if its to hot the bearings are to tight. Hope this helps

You'll never wreck taper roller bearings by having 'em a BIT too slack, but sure as eggs you'll wreck 'em by having 'em a BIT too tight.

275,000 kms - Nissan Patrol wheel bearings all round, never had a failure ever.

Thanks everyone for the info. It seemed strange but I thought maybe there had been a change in the GU compared to my old GQ.

As I brought it second hand in 2004 I had nissan do a 40k service to get a starting point. So I thought why not ring them and tell them what I found- both sides done up extremely tight, seals on both sides ripped one with the spring sitting in the hub and two of the king pin bearing seals rolled over backwards when fitted. Yep it was 2 years ago and 40k but I at least wanted to let them know, said from word go wanted nothing it was just feedback. Do you reckon they became defensive????? Now I know why I've normally serviced my vehicles for the last 30 years.

Still it shows just what tolerance there is when setting the wheel bearings. These were flogged up tight, inner ace is discoloured as is the axle. Went all over the top of WA like this and they didn't fail. I think it was just damn good luck but maybe the tolerance isn't as critical as we think. Knowing my luck now they are set right they'll fall apart.
