Caster adjustment

Post by chambers360 »

So i just got my car back from having a full suspension setup, to see if they could find why i have negative caster on one front wheel, they say theres nothing damaged and cant understand why the wheel is sitting towards the rear, but they say if i can get some adjustable tension rods? Then thats the only way they can rectify the problem so my question is... Can someone point in the direction of the part hes talking about?? Cars a 94 rev3 tubby

Thanks

These are the sort of thing to allow you to adjust the caster, they are called tension rods:

However one thing you could try instead is to simply change the front bush on the standard rods you have, better still install poly versions at minimal cost.

Yes, you could use the Rev1 setup.

However I don't think this is the answer. If you have negative caster on one side only, then you have a problem somewhere - something must be bent or way out spec for there to be negative caster on one will only.

Fitting adjustable tension rods is basically like putting a plaster on an open wound. Unless by chance it's your existing tension rods that are the problem.

This,

Something is clearly bent, or wrong


That aside, you can swap to a rev1 set up as stated above, or if you're capable you can cut the bush end off a rev 2+ tension rod, thread the end, screw on a LH/RH threaded turnbuckle and then a rose joint into that, a couple of spacers to centralise the joint in the original body mount and there you go, adjustable rose jointed tension rods for less than £100

Would a rev 1 tension rod fit? I thought they was different, yer i know something must be wrong somewhere but its been to 3 different garages now and none of them can pinpoint it, i could just put new rev3 ones on and see if it is the existing one thats the problem but if a rev1 will fit and is adjustable... Cheaper than spending 300 quid on aftermarket ones

Are you sure the bushes don't just need replacing?
That's the cheapest option surely.
You should be able to see if the bush is not central.

What's the deal with the Rev1 tension rods? Is it a straight swap, and is it worth putting them on before getting the suspension setup?
