Rental Of Tool For Rear Wheel Bearings

[kepperly]

WAYNE HAVE YOU CONDIDERED RENTING PART # PEL-TOL-SIRB90-P2. i,M SURE THAT IF I BOUGHT ONE I WOULD ONLY USE IT ONCE AND IF I BOUGHT THE PARTS FROM YOU YOU SURELY WOULD GET BACK THE TOOL IN EXCELLENT CONDITION AND BE ABLE TO RENT IT TO OTHER PELICANITES.

Keith,

Having recently taken apart my rear suspension to replace the bushings and rear bearings, I am not sure that you need the tool set.

What you really need are some pry bars, as John Walker mentioned, to push/pull the hub off and then you need a large threaded rod with bolts as well as some metal plates to R&R the rear bearing. All of the above shouldn't cost more than $25.

Follow Kurt's instruction plus do a search on the board. I can dig it up for you, but someone else posted detailed instructions on how to do the job.

No need for it.

To get it out, heat the suspension arm around the bearing with a propane torch, it'll practically fall out then. May need a few light taps with a large socket on an extension.

To get it in, freeze it, heat the arm again, it'll slide right in. Use a threaded rod with large washers to pull the hub into the bearing.

I did this a few weeks ago in a cramped space... Cost - $7.00 in materials, works every time...

To get the hub out of the bearing, I just pound out the inner race with a socket that just fits (with the old bearing in a vise), then make small cuts on the remaining bit of race on the hub, then whack it with a cold chisel, it'll split.

(Your mileage may very, batteries not included)

cstreit,
i just didn,t want to pull the swing arms and disturb the corner balance and alignment. Don Plumbly advised liquid nitrogen but thats a little exotic so I'll probubly go with a propane torch and dry ice. I'll try to take photos and post from our Porsche Shack.

To veiw our meager Porsche shack go to PCA.org and zone 10
wichita region PCA and some of our "tech" sessions, The one on 993 oil filter replacement was pretty funny.

and bye the way Wayne thanks for your timely reply to the initial
tool rental question. Maybe I should shop around before I buy the half shafts and axles.

[Don Plumley]

Keith - I was just extrapolating the take the bearings and put in your freezer suggestion, not recommending liquid nitrogen! Sorry...

[cstreit]

No need to pull the a-arms with my method. Freeze bearing when putting the NEW one in... The old one will drop out with heat on the a-arm...

[kepperly]

thanks all of you that have posted, my ears perk up kike a show dog whenever you guys chime in with your experience. Stay tuned to the Porsche shack at zone 10 wichita PCA for the upcoming tech session to replace the afore mentioned parts.

Chris/Neil:

Do you have a picture of the arrangment you used with the threaded rod and washers. I am going to be doing this soon and would like to see what worked for you. Or, just what size was the threaded rod and how big are the washers.

Thanks, Rich

[Neilk]

Rich,

I was redoing my entire rear suspension, so I took the arms off and brought them to a mechanic with a press. I am not quite sure how big the threaded rod needs to be, but once you take out the drive shaft, you should have a good idea of the dimensions.

Read this post for detailed instructions on how to R&R the bearings. They really helped me when I brought my trailing arms in and assisted the mechanic with the R&R.

Also, John Walker mentioned using 3 foot pry bars to get the hub off.

[CJ]

Just got my hub off last night. Used a large slide hammer with an attachment bolted to the wheel studs. 3 whacks, 30 seconds.

[Rich911E]

Thanks for the help -- it is a project I need to get around to. The link was a big help.

Rich

[cstreit]

Rich,

I just use a bit of hardware store threaded rod, about 1.5 ft long... The washer that sits on the inside (against the bearing) was as big as I could get it, basically it just has to be big enough to cover the inner race. THe washer on the outside is just big enough to sit on the hub inside the hub-centric tabs... (No pics though, sorry)

So for the swap I:

1. Remove the half-shaft and stub axle
2. Pound out the inner race and hub with a large socket and extension.
3. Cut or burn off the inner race from the hub.
4. Heat the a-arm up with a propae torch and it comes right out.
5. Freeze the bearing and re-heat the a-arm to fit in the new bearing.
6. Use the threaded rod with the inner washer that covers the entire inner race and outer washer that fits to draw the hub into the bearing.
7. Re-fit the stub axle and half-shaft...

PITA the first time, simple after that...

(5 lb sledge makes quick work of getting out the inner race)

[CJ]

FYI

I have a rear wheel bearing in front of me. If you are making tools, the ID of the bearing in roughly 41mm. The OD of the inner bearing is roughly 56mm. The OD of the of the entire bearing is roughly 80mm.

Hope that this helps.

[Neilk]

Chris,

For Rich's sake, can you measure in ID of the hub? It would suck to get a threaded rod that doesn't fit inside the hub.

[CJ]

I don't have the hub in front of me, but I can post it on Monday.

[Rich911E]

CJ/ Chris & Neil:

Thanks. As soon as I get my silly timing chain problem sorted out, I will do the wheel bearings. But this sounds like a great subject for a tech article. Rear wheel bearings are really expensive to have done at a shop and this is something that I (and perhaps others) would like to do by ourselves.

Rich

[CJ]

Check that, Judging from my hub, max 30mm threaded rod should work.

Wayne g// da// it why won't you post a reply, you see many people telling me how to make one out of scrap parts! Why the
F??k don,t you just rent one to who ever needs it, could be another source of revenue( i'm sorry I know you are just in it for the love of Porsche). You no doublt have already cabaged onto to
one for your personal toolbox and wrote it off for research as far as the IRS goes. ARE you so paranoid you don,t think someone would return it. I just want to do it the right way w/ 0% of a FU!

Yo Keith,

Mellow out!! Everybody here was trying to help you.

The kit you saw in the tool section is nothing more that some overpriced "scrap parts" as well. If you do a little research using my screen name, you will see a post where John Walker says the horse shoe-like hub extractor won't work on our cars. If that's the case, all that is left of that kit are a bunch of threaded rods and washers, ie scrap parts.

So stop *****ing, get the parts we recommended and get on with it.

Don't be such a *&&%%. I hardly have time to read *every* single post here. If you need to get in touch with me, send me an email. You people need to use some common sense, I can't stand it when people just assume that I have read every single post here - I do have a wife and a life beyond this BBS...

As for tool rentals, it's too much of a PITA. People destroy the tools, don't return them, leave bad credit card numbers, etc. Too much work...
