Castor correction advice please

[timbo2410]

Hi again everybody, well had the wagon in today for it's 60000 service. All's well apart from the advice to get a castor correction kit fitted urgently as it not only trams badly (which I already knew and thoroughly enjoy the terror), but it's also eating the tyres pretty quickly. Dunno why the kit wasn't fitted as part of an Ironman install (had a load of issues with the installer), but I have been quoted $700 for the kit and fitting. Does that sound about right? I've had a 2 inch Ironman lift (springs, shocks, damper and adjustable tie rod). Any and all advice most welcome

If I was going to get correction fitted I would go for the Superior radius arms. Probably end up cheaper in the long run, but it is your money.

It is interesting that you are chopping your tyres out. I ran a 2 inch lift for a couple of years and had no such issues. Just had a good wheel aligner that knew his job.

Sorry? you have a 2" lift only yeah? and someone is telling you you need a $700 Caster Correction? Dont go back to that guy. What are they selling you for $700?

A 2" lift barely needs caster correction and 80% of cars dont have any. it really is an "As Needed" basis for a 2" lift. That being said given your need for a minor correction your options are very very small. Basically you are limited to caster correction bushes in the radius arms only. That is all i would do. If you had 3" lift then go drop boxes IMO. Get another opinion, your being robbed.

Why did they fit an adjustable Tie rod? or do you mean Drag link? (Front of front diff is Drag Link).

Consider Radius Arm bushes and also 1 new Rear Brake line. Fit the current rear brake line to the front and chuck the front and the new line to the rear. a 2" lift is the limit for the factory brake lines and under full flex you will be stretching them out.

I'm sorry it was drag link (forward of front diff). When I bought the car the suspension had sagged very badly and I had the dreaded wobbles at highway speeds. Went to the local 4x4 centre (Ironman) and was told I needed new springs, steering damper and drag link to correct this . Instead of going for standard springs I could go a 2 inch lift. No problem there. I had the car back and the driving difference was amazing. However, the car trams badly. At this service (at a different mechanic), I asked about the problem. The advice was as above. A castor correction "kit" and 3 hours to fit it. Total of $695 estimate. I did ask about brake line lengths, rear anti-roll bar hangers and the rear brake proportional valve but was told that they didn't need doing.

I am not really a fan of Caster Correction bushes either to be honest. Factory rubber bushes for me all day. But, you have very little choice here. at a 2" lift there is simply no other way to do any caster correction other than new radius arms which are expensive and overrated for a 2" lift. Accept that the bushes will chew out and you will be replacing them fairly often.

Call your local Pedders and ask them for a price over the phone for radius arm bushes on a Patrol fitted. or call any 4x4 shop and get a price.

GU caster tolerance +/-1 deg from memory. Rule of thumb 1 deg caster correction per 1" of lift. U may not need them. Mine 2" lift bought 2 deg polyurethane caster correction bushes ($100 ebay specials), 90,000 ks ago still good. Do not go hard core off road but do my share of tracks and corrugations for sure (my dirt road to gate would sort them). Maybe just get a good whl alignment first up just to see results & go from there.

U could buy bushes (have in hand), go to good steering & suspension SME to check current geometry and fit bushes if req'd for 2"lift.

Local Koni distributor / alignment shop charge me $270 / 5 yrs ago for alignment($65) + fitting of bushes ($205). A bit of cost escalation expected for sure + $100 purchase for bushes.

Also, would not go RTC dampener, good HD do the job well.

$160 for offset bushes From patrolapart. I retract what I posted earlier, but I don't like the idea of these offset bushes. Anyway labour to do the job is always expensive.

As for the proportional valve, I made a bracket and fitted it with the lift. Easy as. A length of steel 3mm by 25mm strap and drill 4 holes.
