Perentie heavy duty rear drive flanges

[Unison]

Good evening all, thinking of putting heavy duty drive flanges on a perentie. I've just returned from Vic high country and lost one of the rear plastic caps. Thought heavy duty drive flanges would be better.

1. Anyone recommend a brand of flanges? There seem to be a few out there.
2. Should I replace axles with heavy duty ones at the same time?

Any help would be appreciated.

I have them.

But now in favour of using the LR part as a sacrificial component of the drive train. Keep a couple of spares flanges and circlip pliers in vehicle. Easier to change than a shaft or CV.

Also look at making the bearings and drive flange oil fed to extend its life.

I agree on using heavier duty axles and keeping the standard drive flanges and rubber caps. Rubber caps are cheap and last several years at least if you buy the genuine ones.

I’d go heavy duty axles and drive flanges.....my old defer never needed a sacrificial drive flange and never damaged anything upstream.

Can think of better things to do than replace a drive flange in the side of the track.

I dont think I ever saw a stripped out flange on a perentie when I was fixing them for a living,

plenty of fried halfshafts and the odd Diff..

They don’t work as a sacrificial part. They fail from wear not from overload.

Thats where the screw cap flanges are good. No oil leaks.

That’s what I meant. They wear faster than or before a HD shaft will wear.

That’s definitely an advantage.

I bought a 300tdi diff, and when I got it Hm found a previous owner had welded the flange to the end of the shaft. Because the flange was worn. [emoji1]

HD shafts or flanges never wear. It is just the stock junk stuff.

As Dave said, the old oiled ones never wore at the splines, but they would snap axles just as easily as the later ones.

[slug_burner]

The flanges flog out due to a lack of lubrication. A known problem for grease filled hubs. Older Landies used the diff oil to lube the wheel bearings. Change the grease seals to double lipped oil seals and knock the seal in the axle tube that goes around the axle shaft out. This will provide lube to your splines as well as the wheel bearings. When I did this modification I used the Maxidrive heavy duty axle shafts and flanges the ones with the “X” in the part number have a longer spline for more engagement and reduced pressure per length unit of spline. These are the parts https://www.allfourx4.com.au/Drive-Flange-Rear-Heavy-Duty-Maxidrive-Defender-to-2002-Aftermarket-HTE859X and they mention the fact the that flange has to be used with the matching shaft.

Look up oil lubed wheel hubs and you will find a lot written on the topic.

I do recall reading a while ago that lot of perenties already had maxi drive shafts fitted by the army?

nope.

oh By the by....


remember when getting flanges that there are old spec ones and new spec one,s the new spec ones have a wider flange on the inside and will not fit inside the hub.

yes photos and measurements to come.

yes I did waste an hour and a bit at work pulling all four rear flanges off of Arkie only to find that I had forgotten this.

Yes, I've been here before.
