Re: Shimming axles
Should be no problem. With or without shims, tighten nuts, run around the block a few times, re-tighten. Do this a few times to insure seating. Recheck from time to time.

Re: Shimming axles
When fitting the rear hub with or without shims, it is VITAL that the axle, hub and shims if they are going to be used are absolutely free of any grease or oil. They are supposed to grip on the taper. Any lubrication (even the slightest amount) will prevent that happening.
BTW, check the condition of the inside of the hubs where the rollers run. There is usually wear at the axle nut end. If that is trough the hardening, replace the hubs or you will break an axle.

Re: Shimming axles
Shims will work long enough to get the car to a used car lot to sell it.

Re: Shimming axles
Shim material is usually soft enough that a person would have to continually retorque the axle nut to keep the joint from coming loose. Any movement in the joint, no mater how miniscule, just allows the joint to get even more unwanted clearance over time. There are still good axles out there. Better to find them sooner than later.

Re: Shimming axles
I guess here to with the use of shims there are many different views.
Multiple shims being needed I think could be a real concern. However, using one, and torquing axel nut to 100 with a good key, I don’t believe should be a problem. On the drivers side rear of the 29 that we have had for 42 years, things have been fine. Many miles, many years, checked a number of times, no issues. Just keep checking the torque Happy New Year! |

Not sure where the 100# torque specification comes from but that is not a number that Ford recommended. Furthermore, if you are checking the torque on a frequent basis for over those 42 years, then kudos to you however that is highly unlikely to be the protocol for most Model-A owners who seemingly do not even take the time to check oil and coolant levels on a regular basis, ...much less the lug nut torque on each wheel. |

Re: Shimming axles
Different torque charts will have various numbers for that size axle nut but most will be around 200 ft. lb. or more.

Re: Shimming axles
Check Les Andrew’s book. Rear axel nuts 125 ft/lbs.
I don’t know what Ford spec might say, but I have been told for many years 100 was the right number. Has worked for me for years. Using a shim to stop the brake drum from hitting the backing plate has been used by owners for as long as I have been around Model A’s. If the axel is not really worn, why not. Most of these cars are not driven hard or many miles. When I had our cars brake system completely overhauled 5,000 plus miles ago. Mechanic used one shim on drivers side axel. No problem as of now. I check torque on rear axels every 500 miles. Not a big job. Gives me something that I can still do. As with many other things, we can all have different views. Enjoy.

Re: Shimming axles
I don't think the Ford dealers owned torque wrenches but I believe that the instructions were to use a long wrench. In any case the nuts should be tight. Plus I agree that the hubs should be put on dry. I have used some Loctite after cleaning with acetone, the red thread locker that is designed to be removable.
100 foot-pounds is probably too little and 200 foot-pounds may be too much. I have settled on 150 foot-pounds and then tighten more to put in the cotter key.

Re: Shimming axles
Also on my particular car I think the po handled the rear axle similar to the front spindles they tightened and backed off two slots on nut .Probably saw bearings in rear hub and thought that what they were supposed to do. This car has the Boling hydraulic brake system on it, this probably damaged the new hubs, was also missing rear seals and snap rings.

Used Loctite bearing mount when I shimmed my axles

Re: Shimming axles
I was told by an old drag racer that a little chalk dust on clean, dry, well fitted axles was the hot tip. This guy was also a skilled machinist.

Re: Shimming axles
Hello again, did a search on axle shim on the forum , many posts on this subject. I believe in my case the shims were added as it was converted to hydraulic brakes and without out shimming, the brake drums rub against the back plates this seems to be common on hydraulic conversions .The alternative may be remove depth of the drums but will have to check to see if the brake shoes also have clearance, along with the seal not hitting inner hub.another possibility is to put a shim or spacer between the hub and drum as they are separate pieces on the Boiling conversion.
