Title: Oversteer - front springs?
Post by: Shackeng on 09 June 2012, 18:26:54
I've noticed in the last month or so that my TD Estate oversteers more than usual on a RH corner with slight adverse camber that I use regularly. I had it WIMmed about 5K ago, and there is no abnormal tyre wear, so I don't think it is the setup. The car is now on 115K and I suspect that the front springs may be due for replacement. Any thoughts? :-\

shocks as well?

Don't neglect rear - broken rear springs/shocks can oversteer.

Should add, AFAIK, my old TD saloon did 140k on original springs with no handling issues. :)

Good point, I'll check for breaks tomorrow, no sign of leaks from the shocks, and certainly the front end doesn't 'bounce' when checked for failed shocks, and which I would change with springs as a matter of course. :y

My TD Estate has shifted some heavy loads, so I would not be surprised if it was time to change Zebedee and his pals. :y

Considering the price of GM springs, and how good I think they are, I would only change fronts if they developed a fault.  Hmmm.  I changed my MV6 fronts around 30k ago, as ride height was shafted, and on removal, one was longer than other (but neither broken)

Sorry, that didn't make sense, did it.

They are normally really good/reliable, if a tad soft. But when they fail (either break or dramatic length change), its normally fairly obvious.  Additionally, I am traditionally quite hard on springs/shocks/suspension/steering. Roundabout City doesn't help.

That comes as a complete surprise. ;D ;D ;D :y

drivers side on my old TD estate was consierably softer than passenger side, did post up on here upon changing the slight pull to the right which had aways been there was completley cured,
y theory is as car has mostly just the driver in it, the springs do degrade!!

Seems to be passenger side I wreck first. Probably bloody roundabouts...

it been proven you tend to go faster round a right hand bend than a left, because you feel safer!! on left hand bend you are closer to the road surface, so you go slower,just in case it falls over!! hence you wear left hand quicker!! :y

If anything has gone on mine its pax side, and I still suspect the front :y

Any folding or tucking sensations from the front? Especially when manoeuvring on full lock when parking. Check rearward wishbone bush if so. Iirc you have polly fronts?

Not pollyed at present (on the shelf on stand-by), as new Lems fitted last year, so I doubt the rear bushes have gone yet, and I have not noted that effect. :y

Ah, must have been the roll bar bushes you showed me then. Your welcome to bring it down if needed, see what we can find. :y

I'd say rear issue if oversteer :) worth checking drop links all round too though :)

Thanks Chris. No you did see poly front bushes, but they were in my cr*p Delphis, which subsequently failed rear bushes, hence new Lems, and keeping the polys for when the front bushes go. I will probably not get round to looking at it for a couple of weeks as I am away and will use the 3.2 Elite:y

Thanks G, front droplinks replaced last year, but will be checking rear springs etc. as advised above by TB. :y

I've had it up on stands this AM and all springs and shocks appear sound on pax side, so perhaps it just needs another set up. I only notice this oversteer on one particular, downhill, RH, adverse camber corner, so maybe I'm just being fussy. :-\

What happens if you swap tyres, front to back?

Funny you should say that, I have still got winter tyres fitted, which was the next issue to tackle. :y
