Replacing/upgrading 4 lug axle hub

I want to raise the clearance and go with a five lug 16 inch wheel. The tiny stock wheels and the lack of clearance give me gas.....

As such, Looking for a source for the hubs.

Will stock 5 lug Jayco hubs work on a 4 lug axle? If so, anyone know the outside diameter and lug pattern? I'd like to be a little anal and match the wheel with the tow vehicle.

I'm thinking that step one is to figure out exactly which axle you have. Then, the axle manufacturer could tell you if a different lug pattern hub is available. It's probably a Dexter axle; here is a pdf of their axle identification guide: http://dexteraxle.com/i/u/1080235/f/...ation_9-10.pdf

Remember to check carefully for wheel clearance.

Good Luck!

My original 19ft TT had very poor ground clearance as well. It was so bad, its rear plumbing drain pipes had drag marks on them. An early indication that its rear end (and overall chassis clearance) needed more ground clearance. For this low cost adjustment, I simply re-positioned its axles "under" its leaf spring packs. Very simple task that created 4.0 - 4.5" more ground clearance - using its original tires and axles. Only needed to purchase some 10 Guage brake wiring and 4 x axle saddles. While doing this adjustment task, I also replaced its worn out spring bolts and installed new plastic bushings. But from a base adjustment (using original items), it cost me under $100 (including welding costs).

If wondering, I simply followed instructions within: http://www.rverscorner.com/articles/axles1.html

Hope this helps in your research....

If your trailer has a Torsion axle system, one can install a "low cost" steel spacer. re: 3x3 steel tube or perhaps a 4x4 axle tube (based on your trailer's frame size).

For a few pictures, surf:

Note: If torsion axle is more then 20 years old, the axle needs to be replaced. Torsion axles older then 20 years are unsafe. And, need to be replaced.

Hope this "low cost" solution helps in your research as well.

It's a torsion tube, no brakes. The spacer idea is one I am contemplating. I am getting a quote from a noted adapter maker for a 4 lug 4 inch on center to a 5x130mm wheel.

I'd RATHER find a larger diameter hub and then drill and press in studs......

Just for giggles, what does a new torsion tube run?

The cost of a new Torsion axle is regional specific (and size specific). If buying a new torsion axle and your current torsion axle is 30 degree, do investigate a 45 degree replacement. Thus, a steel spacer (to add more clearance) might not be needed.

To estimate Torsion axle replacement for your region, simply call a few local welding shops in your area. And, your local Camping World store (as special order item) as well. http://www.campingworld.com/ Each will provide an estimate.

Perhaps one can replace the existing Torsion "hubs" with different bolt pattern hubs as well? Your local RV Centers or most Trailer Supply stores could measure your current axle / hubs, and provide their recommended replacement costs as well. re: Only replace the hubs - if Torsion axle is under 20 years old.

If you want brakes on your trailer (IMO, all trailers over 1,500 lbs need their own brakes), replacing with new Torsion axle "with brakes" is your best solution. re: All parts from same company (like Dexter) and being a bundled product, it should have the best pricing as well....

Hope this helps as well....

Getting close....it's a 93. Just finished pulling the axle, watching da game now....will look for a manufacturer marking later.

Thanks for the suggestions.

Just so you know I'm not a nutter and someone recognizes the 5x130 lug pattern....

For Dextor Torsion design axles, lots of info within:

http://i.b5z.net/i/u/1080235/f/Torfl...ation_4-04.pdf

Note: They call their Torsion axles "Torflex". As seen in this .PDF file, lots of measuring to do - before calling others for replacement estimates.

Happy shopping....
