944 Geek Posted 16December, 2016 Report Share Posted 16December, 2016 G'day 944 guys, has anyone done the rear wheel bearings in their early 944? It seems like a straightforward job with the exception of the 350ft lb stub axle nut. Any tricks to this?Also apparently the stub axles get damaged by the inner race. I can get the from 944 online but just wondering if anyone else has found this? Just trying to clue myself up before doing the job.Any help will be appreciated.David!

Rod C Posted 16December, 2016 Report Share Posted 16December, 2016 I attached a 4ft length of pipe over the end of a spanner as leverage if that helps on my 924 Link to comment Share on other sites More sharing options...
Rob Posted 16December, 2016 Report Share Posted 16December, 2016 Geeky, I did this last year with my 952. With corrosion and time, the torque required was >> 350lb-ft. Have a look at the pics from my dramas here... (some scrolling required...) Link to comment Share on other sites More sharing options...
time Posted 17December, 2016 Report Share Posted 17December, 2016 Hi, I recently did this task on an 82 944. While driving over bumps the left rear bearing was occasionally clunking. I found this was because the outer bearing had dented and ovalised the bearing mount in the steel trailing arm, but the shaft was perfect. Actually they both were, including the races.I had to buy a 1-38 socket, and as RodC said a length of pipe. I found pressing bearings in - in situ a challenge.I was able to buy high end bearings and all the seals at the local bearing supply.Best luck Link to comment Share on other sites More sharing options...

Mine just have a little bit of movement when I use a wheel spanner for leverage but they are making a low frequency humming noise which sounds like bearing wear.I got a bearing kit from Allied bearings in Cairns and I am just preparing mentally to do the job.

My torque wrench only goes to 200nm and 350ftlb is 474nm Link to comment Share on other sites More sharing options...
Timm Posted 17December, 2016 Report Share Posted 17December, 2016 On the topic of wheel bearings...have you guys noticed any pad knock back with worn rear wheel bearings?I'm getting a low brake pedal after hard cornering. My front bearings are fresh and tight, so I'm wondering if my rear wheels bearings are getting a bit loose. When I jack the rear up and try to wiggle the wheels, they don't have any play though I'm obviously not strong enough to replicate the forces of hard cornering.

Rob Posted 17December, 2016 Report Share Posted 17December, 2016 Timm, check the tension on the rear nuts - they are known to back off, believe it or not! Link to comment Share on other sites More sharing options...

My torque wrench only goes to 200nm and 350ftlb is 474nmNo wear on Stubbs and I haven't tensioned up the nuts yet but I'll be using the wrench and pipe method again.

My torque wrench only goes to 200nm and 350ftlb is 474nmIf you have a (for example) a 4 ft bar and you weigh 90lbs, that would give you 360 lb-ft if you stood on the very end of the bar (using a breaker bar or similar, not your torque wrench). If you stood on the 3ft mark, that would give you 270 lb-ft. Just substitute your weight to get the position on the bar to apply it... Link to comment Share on other sites More sharing options...
tazzieman Posted 18December, 2016 Report Share Posted 18December, 2016 I borrowed a friend's truck&bus torque wrench. You can tighten up hard then visit your local truck service shop for the final torquing. Link to comment Share on other sites More sharing options...

Rob Posted 18December, 2016 Report Share Posted 18December, 2016 No - the stub axle nut. The chap who bought my 968 mentioned a sudden increase on wheel bearing noise and he found the stub nut had loosened off. Not my work, but done by a reputable repairer...

I grew up fixing aircraft so I am a bit of a stickler for precision but your method will work nicely until I get access to a torque wrench big enough.

tazzieman Posted 18December, 2016 Report Share Posted 18December, 2016 Put some white out or paint over the stub nut when done. I do that with cv bolts too. Link to comment Share on other sites More sharing options...

The book says 36 and I have just bought one. Does anyone know for sure? Link to comment Share on other sites More sharing options...
time Posted 11February, 2017 Report Share Posted 11February, 2017 Hi, I brought a 1-38 imperial socket as it was the best fit......I brought from an engineering company not Bunnings. It works brilliantly which is good when ones whole body weight is standing off it torqueing the nut down.i would be really happy to post it if anyone wants to borrow it. It doesn't fit too much.

944 Geek Posted 22February, 2017 Author Report Share Posted 22February, 2017 Wheel bearing WTF?Having replaced my rear wheel bearings,(not difficult-just had to buy a big breaker bar and 36mm impact socket) and taking my lovely car on a road trip Brisbane-Sydney-Melbourne, Adelaide, my new rear wheel bearings are singing to me louder than the ones I replaced...New bearings from Allied, packed with the correct grease, properly torqued thanks to a truck tyre place.I spent my younger years an an aircraft maintenance engineer, so I am not unfamiliar with this kind of work but this one is weird.WTF? Anyone got any clues? Link to comment Share on other sites More sharing options...

944 Geek Posted 23February, 2017 Author Report Share Posted 23February, 2017 I don't think so. The sound seems like a classic bearing sound and doesn't vary with road surface. Weird... Link to comment Share on other sites More sharing options...
