Lehman FLH Rear Drive Issues

[bones1]

Well I pulled both rear wheels off of my Lehman/Ultraglide searching for noises and found them. Both axles have over a inch of play when rotated before they engage, whatever is in that big black drum rear. I can tell axle bearings are probably gone as well. Is anyone familiar with these drum brake solid rears?. What will happen when I unbolt the 4 flange nuts to remove the axles for new bearings or is the rear too far gone to worry about Bearings?.What's in there?.

Can anyone tell me what will happen if I pull the axles on this Lehman Renegade rear end?. Is there a set of gears in there?. I need to replace the bearings but have never seen a rear like this one.

If the axles have a plate with 4 bolts and nuts on them you will be OK to pull them out without any problems

Yes sir, they have a small 4 bolt flange to pull them.Not being familiar with this type rear I assume the axles are splined but there is obviously no ring and pinion, just didn't want parts coming apart in the rear itself. There is also a metal to metal noise in the rear itself, I would imagine bearings are there as well as the axles. Boy, a breakdown drawing of this type rear would be very helpful but I can't find anything online. Thank for your reply sir.

I have seen this rear end before, I dunno who makes it but a Frankenstein (early model) had a similar set up

Nothing will fly apart on you when you pull the axles, the axle bearings are worn giving you the in and out movement.

Get the axles out and press the bearings off, there should be a part number on the bearing, go to an Auto parts store and match it up, it could also be a DNA rear end

I am using a puller that you smack with a hammer and so far it will only come out 1/8 of an inch. It's having a hard time coming there the backing plate it seems. The bearing looks trashed though. Bigger hammer time. Thanks for you help so far.

I have replaced outer bearings in ours. Looks like yours. Remove brakes, remove 4 bolts axle should come out. Hopefully you didn't tear up end off housing where bearing fits. Take axles to a machine shop to press the bearings on and off. Local napa store had bearings.

Thanks for the info. I got one axle out tonight housing looks ok but the splines on axle are worn a bit. Do you know what is in that rear, what do the splines engage in?.

 

[bones1]

The bearings are bad but something else in the rear itself is awful sloppy where the axle splines engage. More bearings?.

If this is a traditional rear end it has carrier bearings that could be badly worn also

Thinking your rear is the same as champion from when lehman bought them. Never had mine apart. Behind that lower red plastic plug when turning axle should be a grease fitting takes a couple pumps from grease gun once or twice a season. Maybe thats all thats needed.

This looks the same. Dna trike axles

Thanks, I will check for the grease fitting, I did see two red plastic plugs, one on bottom and one on the side.I did run a scope in the axle and there are bearings in there as well. Looks like you to remove the whole rear to get in there to replace them, there is zero information as to whats in this rear.

 

[bones1]

Yes it does look like the DNA but it is different, I contacted them earlier to see if it would replace the Lehman, no go. Papa it is a 2004 Harley Ultraglide, no idea on the kit year. Looks like the body comes off soon...I hope not. Even if I get in the rear the only thing available will be the bearings, hubs diff etc n/a. May not be worth it.

The 4 bolts

[Jack Klarich]

The 4 bolts and nuts hold the axles in, the splines if badly worn will cause bad JUJU for you, a bit of in and out end play is needed, if yours are excessive the movement may have caused more damage, do you have pictures of the axle and bearing?

 

[trike lady]

I managed to find a photo of the axle and it has drum brakes. From the way it looks broken down, the axle splits in half, the pulley goes inside the housing and it clam shells. Your going to have to pull the axle and rebuild it. This is the best pic I could find.

Excellent,good job finding that.
