RPR Posted November 16, 2007 Share Posted November 16, 2007 Having put 2+" springs on the new (to me) Disco, there is definitely some increased castor related wander, despite my thinking that the winch and second battery would sit it down enough for this not to be the case. Is there anything to "castor correcting" bushes, or is it hype? Since I have never heard resounding endorsements for any polybushes (and have never used anything but standard rubber jobbies), if there is something to be said for castor correction bushes, is there any make that seems more flexible and closer to standard than others? Thanks. Below is the vehicle in question: Quote Link to comment Share on other sites More sharing options...
David_LLAMA4x4 Posted November 17, 2007 Share Posted November 17, 2007 I only know 2 people who have ever bought them... 1/ Sold them before fitting them and put the money towards some cranked arms 2/ Fitted them and said that they did seem to have corrected the castor but then did the usual poly thing and only lasted 5 minutes because he actually expected them to work at full articulation A foolish though not uncommon misconception of using poly rather them OEM bushes.

LR90 Posted November 17, 2007 Share Posted November 17, 2007 Can you live with the wander? If you correc tthe caster using bushes or cranked arms you'll increase the chance od prop vibration and then your into double cardon props and more expense. If you really feel you must correct it getting the swivels slotted is probably the best route to take. Quote Link to comment Share on other sites More sharing options...
RPR Posted November 17, 2007 Author Share Posted November 17, 2007 Thanks. Snake oil it is. I can live with the wander, but I'm not sure if the Sandbag can, and this one is hers... Quote Link to comment Share on other sites More sharing options...
streaky Posted November 18, 2007 Share Posted November 18, 2007 Hi Richard....long time & all that. Are you sure that it's castor related? Them tyres look mighty tall and could give the impression of wander? Another point...non-related. I note you have a steel rim as the spare and alloys on the car. If you have to swap one over you'll need the correct wheel nuts to secure each one. Regards. S. Quote Link to comment Share on other sites More sharing options...
RPR Posted November 18, 2007 Author Share Posted November 18, 2007 Thanks Streaky. We're coming to Dubai for Christmas. It would be great to catch up with you and the other reprobates. I'll PM you. Quote Link to comment Share on other sites More sharing options...
Griff Posted November 19, 2007 Share Posted November 19, 2007 Instead of wasting time with castor correction bushes, have you considered "clocking" your swivels? Remove them, mark the standard bolt holes, weld them up and mark new holes 3-6 degrees around. This rotates the swivels rearwards and makes for a etter job than slotting the holes which has been marketed in Australia. For a 2" lift you would only need 3 degrees.

Exmoor Beast Posted November 19, 2007 Share Posted November 19, 2007 Our Discovery has a 2" lift and 235/85x16 BFG ATs and it runs dead straight with no wander whatsoever, it may be worth trying a set of someone elses tyres before altering anything just to eliminate tyres.

Gromit Posted November 20, 2007 Share Posted November 20, 2007 Our Discovery has a 2" lift and 235/85x16 BFG ATs 110 with 2" lift and 255/85R16 BFG MTs and I've a bit less self centering but very little wander, most of which I reckon is caused by the knackered bushes in the radius arms.

Bull Bar Cowboy Posted November 20, 2007 Share Posted November 20, 2007 Richard, Definitely not snake oil, but I guess its all in the quality of the bush ……………. The offset correction bushes do their job OK of rotating the axle back to its correct position, thus correcting the castor angle ………………. The only ones I have any experience of are superpro, and the quality is excellent and they have a 3 year 60K warranty ………….. I have seen them used very successfully on both Land Cruiser (VX) and LandRover ………….. however, they are not cheap ……….. you are looking at slightly less then 50% of the cost of correction radius arms …………… http://www.superpro.eu.com/ Ian Quote Link to comment Share on other sites More sharing options...

Rotating the swivels should be a perminant fix to the problem. Quote Link to comment Share on other sites More sharing options...
simonr Posted November 21, 2007 Share Posted November 21, 2007 If the truck is wandering - I would look at worn bushes first. If it's lack of self-centering of the steering wheel - look at your toe-in / out. If neither of these fix the problem then look at castor correction. However, it's unlikely to be necessary for a 2" lift. Although you get more tyre wear, increasing the toe in/out a little can make the steering fell a lot more positive.

dollythelw Posted November 21, 2007 Share Posted November 21, 2007 We built a jig for clocking landy swivels, its nice and simple - turns it back into a car instead of a shopping trolley. Quote Link to comment Share on other sites More sharing options...
