Lower rear radius rods

So was changing a wheel bearing today and noticed I have a bad bushing on the lower rear radius rod, in board side. So I call my local dealer and was told you need to buy the complete lower for 250 for one lower!!!
Has anyone found a replacement for these, is it even doable?
Really not looking for aftermarket.

Re: Lower rear radius rods

That is why most, myself included, go aftermarket, you can get a better & more specific built part for less, and it’s usually serviceable.

Re: Lower rear radius rods

Some shopping around online, OEM can be found for about $200.

If you go aftermarket, remember that the TRE has 12mm bolts. Most other XP1000 models use 10mm bolts.

Some aftermarket have both sets of bolts and bushings.


Consider getting new bolts too LINKY

You will spend about another $25 for bolts & nuts.

What aftermarket did you go with?
I’m pretty set on the L&W Fab’s. A friend is using them on his turbo with good results so far.

I saw the notes in my service manual about the nuts but not bolts, thought that was weird. So I noticed another issue while in there working, I put a Polaris rear Bull bumper on and noticed some interference with the factory lower radius rods at full droop. I’ll need to change those bolts and nuts as well. Yes I have the 12mm bolts with the 18mm heads. Polaris engineering at its finest lol.

Re: Lower rear radius rods

I need to go check my rear bull bumper. Got the same one.

Mine is sitting in the garage with a broken outer radius rod bolt. Got new nuts, just no bolts. Have 2 sets of nuts & bolts ordered. Keep one set as a spare so I don't have to have a RZR sitting on jack stands for 1-2 weeks.

I followed another tip here on the TRE forum. Get a needle grease gun tip and squirt some waterproof grease into the boots on the radius rods.

I use a popsicle stick and slide it down the boot. Slip the needle in behind the popsicle stick to get "some" grease near the bushings. I did both sides of all bushings.

The popsicle stick helps you keep from poking holes in the rubber boots with the grease needle.

Ordering the L&W Fab kit tomorrow. Can’t save mine and not spending 250 on 1 lower. Kit is 400 all 4 and heim joints.
I’ll post some pics when done.

Sorry but that's not a good "tip". Petroleum based lubricates will attract dirt and make them wear faster. This is even more so the case inside the boot wear they are not water tight and will trap the dirt. A dry lube like silicon or teflon works much better and will not attract dirt.

Oh yep this is very true. Use the Teflon lube, dirt getting up in there is a bad deal, I’ve used it on farm applications a lot, same concept hard working machines in dirty climates. Dirt in bushings.. wear out fast

How hard do you drive it/ how many miles before changing this? I am about to buy the TRE and I didn't know the lower radius rods weren't serviceable. Thank you for that info. is that on both the front and the rear high clearance arms?

Re: Lower rear radius rods

Yes. Bushings are not serviceable on the TRE.

If you are going to use your new TRE in dry locations, you can probably get by for a couple years before you should consider greasing the wheel bearings. That's what I did on mine. I'd lube the boots on the radius rods as well with the teflon rec's listed.

Bought this tool. LINKY for my wheel bearings

This year, with the record amount of snow and run-off in CO, my TRE was more of a Trails & Rivers Edition. I was in lots of deep water for extended periods of time. Try driving UP a river in 2 feet of water for a few miles. I made it. The 2019 Turbo-S, two other XP1000's and 2 more 900's could not.


I was re-greasing my wheel bearings (second time since so much water).

Have to disconnect the radius rods & front A-arms to pivot the hub to get the grease tool in. My radius rod bolt(s) broke second time around torquing them to 100 foot pounds.


When you grease your wheel bearings for the first time, pull the axles as well. Put some anti seize, spline grease, water proof grease, etc. on the axle splines. I had some left over Honda Moly60 spline grease. Specially made for splines. That's what I put on my axle splines.

You will love the TRE! It goes places others won't even attempt.

That is amazing advice. Thank you so much I really appreciate it. when going through the two feet water do you have a snorkel system or anything like that? Is there any areas I need to block off because we will be doing water crossings in the sierras definitely.
