I install Terrafirma 6° front radius arms on my 1997 Land Rover Discovery. Big improvement in road manners on a lifted Land Rover, highly recommend.

I just went through this last year on my RRC. Every single bolt came out without issue, but one. Nightmare. Keep up the good work!

Yeah, the onroad experience sans sway bars can be pretty darn unnerving!! My wife and I were camping down near Carlsbad, CA & she wanted to run to the store quick in the Disco - She never drives the Disco and because I'm so used to it, I forgot how squirrelly it is without the sway bars and the lift!! (it's also a manual trans) When she got back, she was white as ghost because she attempted to get on the 5 fwy but quickly realized she was going to die if she tried going fwy speeds! So there she was, driving like 45 on the freeway!! Poor thing! 🤦

This shouldn't be a thing that ever breaks but my dad was running 3 degree terrafirma radius arm and one of them completely sheared off, became 2 pieces, since both he and I have put caster correct swivel housings on our defenders, probably better as pinion angle is still the same throughout travel as standard, best would be to use the genuine swivels and get them drilled/machined for caster correction

Yikes, that’s scary. I only just recently learned about caster corrected housings, and I like that idea.

Hey bro I have a question for you! So I have a D2 and I'm doing the Terra Firma 4-in lift in about 2 weeks. I also have the Johnny Joint 6° adjustable arms on order my question is how do I decide where to set them at? Part of me wishes I had got fixed ones but I only ordered those ones because they have roller bushings and I thought that was cool. So is it logical to measure the factory angles with an angle finder with it both resting on the ground weight of the vehicle on the suspension and also up in the air suspension fully extended and whatever those Factory measurements are just try to meet that in both positions with the adjustable ones? I have a hard time finding info on this but that's the idea I came up with not knowing much about it. Or my second idea is since it's a 4-in lift and usually 6° is recommended maybe I just contact adrenaline 4 x 4 who makes those and ask them at what amount of threading if any of the adjustable part would automatically make them around 6°?? I'm just curious your two cents haha

Quick question, my Disco 1 is going to life with 2 inches kit so maybe I need 3 degree radius arms? Thank you
@tfrasca1429 ай бұрын
Yeah, based on what the manufacturer recommends, I think 3° arms are fine for a 2" lift. At 3" of lift, I was right between 3 and 6°, and only went with 6 because I may add more lift in the future.

Have you found the 6 degree on a 3” to work well? I was just fixing to order 3 degree today for same height of lift.
@tfrasca14210 ай бұрын
6° feels pretty good to me. I think at 3" lift, we're probably due for somewhere between 3-6°, but if I know myself, there's a good chance I'll go up to 4" springs at some point, so I liked the idea of some extra headroom.

Thank you, please share with your thought on the terrafirma after 9 months? Its interesting, I had similar symptoms to you. But i Solved them with tie rods, steering rod and panhard rods. on defenders with 33" and 25" tyres. Thats why I love LR, no two are the same :)
@tfrasca14215 күн бұрын
As far as the radius arms themselves are concerned, I have no complaints at all. They seem plenty strong enough for me. I do think that 6 degrees MAY have been too much, because now with the 4" lift, I get a slight vibration coming from the front under acceleration.

@craigmclaughlin78706 ай бұрын
Curious if you experienced any front driveshaft vibrations prior to fitting the new radius arms and if you were running a stock front shaft? Often with the pinion angle change that goes along with caster adjusted arms requires a double cardan front shaft to smooth out any vibrations as the stock front driveshaft u-joints are set out-of-phase deliberately at the factory by several degrees to work with the steeper stock front pinion angle of D1’s and late 90’s RRC’s. Changing to castor adjust arms will tend to lower the front pinion angle which makes the out-of-phase stock shaft vibrate due to u-joint harmonics hence the need to switch to a double cardan unit.
@tfrasca1426 ай бұрын
Yup, after I put the lift on, (before radius arms) I had some driveshaft vibrations. A Tom Woods double cardan shaft fixed that.
@andicog3 ай бұрын
Here in the UK you can buy castor corrected swivel housings that correct the castor angle without moving the axle.
@tfrasca1423 ай бұрын
@@andicogthat would have been cool to know. The downside to rotating the whole axle is that it makes the pinion angle theoretically worse for a double cardan shaft. Although I haven’t actually noticed any issues related to that.

@@tfrasca142 I had trouble with noise from my 110 back axle after a 2" lift , only on a neutral throttle, everyone I spoke to said the pinion angle doesn't change with suspension travel, yes, it does! I ended up fitting spacers between the chassis and the trailing arm bushes, it cured it, the spacers are genuine LR, apparently they had trouble on 90 Defenders when fitting H/D suspension at the factory, it upset the pinion angle, even the factory were having trouble! 👍
@tfrasca1423 ай бұрын
That's crazy that anyone would tell you the pinion angle doesn't change along with the ride height. The spacers must have been pretty thin, right? There's not too much extra thread on the chassis end of the stock trailing arms.@@andicog

I'm glad you mentioned this. I thought I had torqued everything down, but just went out to check and found the rear axle to radius arm bushing bolt was loose. I looked at the D1 Workshop Manual I have and the value for that fastener is 197 Nm, or about 150 ft lbs. The larger nut holding the rear of the radium arm to the chassis is supposed to be 176 Nm, which I had done. But seriously, thanks for saying something.
