Will it be possible to replace the rear wheel bearings without a tool like this, or should I just spare myself the grief and purchase this? Does anyone use this particular tool, and does it work well? Any alternatives? Thanks.

In my opinion, even if you only use it one time, it would be worth it. MAJOR pita to do that job if you don't have either that tool, the SIR tool, or a truck stop shop nearby that will do the press work for you (and will probably charge you about the same AND you have to run the rear wheel hubs to them and wait for them to do it). I'd suggest you buy the tool, use it and then re-ebay it if you don't think you'll need to do the job again.

Yes, you need this tool - or one like it to remove the rear wheel bearings. I've heard you can get them out with a blow torch, big hammer and some Tibetian incantations - but that didn't work for me. I bought the other - much more expensive version - and it made removal and installation a snap - especially if you have air tools. I'd let you borrow it but shipping alone would cost as much as the Arnworks tool.

If you can't find one locally, I'd say it's a good buy.

BTW - coming to the 'Fest this year?

 

That is a good price for the tool. You can also buy any generic wheel bearing pulley which will look similar to that one, but will have more adapters etc for different sized bearings. All the audis and VW's, as well as the newer porsches are using the sealed bearings, so the universal tool is nice if you ever plan on doing work on any other cars.

 

All this talk will be in vain however if you can't the the grease caps off.

 

ive done three without the tool - took hours and alot of cussing. Then i used the tool and it was gravey.

 

I used a horbor frieight slide hammer and it worked like a charm and it was cheaper than that tool. Remember to warm things up with a torch and the bearings come out much easier. Both sides took 2.5hrs. Clarks has a good write-up that I followed.

 

Agree, I did two pairs of trailing arms w/o a tool, and what an 'effing pain in the ***. I would not do it again w/o buying some sort of dedicated bearing puller tool.

 

- i did the torch, slide hammer, home made press kit and it worked- about 3hrs a piece- last set i did both in under an hour w/ the tool.

 

OK, tool it is then, thanks guys! What started as a simple wheel upgrade has turned into a real PITA requiring longer wheel studs, pulling hubs, replacing bearings... I've had the front hubs apart a bunch of times, I guess this is why I haven't yet taken the rears apart.

Chip, no can do on the 'Fest this summer. I am spending any extra $ I have on getting the car prepped for the NASA GTS Challenge series. I hope to do my first race later this season. Just got the car back from the cage builder, I had them tweak the cage to meet the new double door bar rule. I'll be thinking of y'all at 'Fest in August though, no doubt. Make a bumpy lap for me!

So, last question...any tips or tricks when using the Arnnworx tool? Anything I need to watch out for? Or will it be fairly self-explanatory once I get it in hand?

 

Looks like the treaded shaft is just galvanized stock. Should be case hardened and the threads reground. The nut too.

 

wow,,,that is cheap i paid 400 for mine years ago...definetly a tool worth having

 

I did the job without the tool, but I did have to go buy a generalized bearing race tool. I say just buy the tool, it's not that expensive, and ultimately worth your saved effort.

 

Already purchased, just awaiting delivery.

 

Sometimes I post without reading the thread... which is dumb.

EDIT:
I have never done the late rear wheel bearings, I've done the early ones. The early ones can be done with generic wheel bearing tools, and I don't think the arnnworx tool applies to this job. But on late cars the arnnworx tool is a must, and will likely work better than any generalized tool out there.
