My 2.5 td estate has become VERY wavy, as opposed to a little bit wavy, in the last 2-3 days.
I think the rain may have exacerbated it, or the feeling of it. But to be honest, i've lost all confidence in it when i'm driving now.
I am aware that the front wishbones needed doing (rear bushes on em are kaput!)
But the wavvyness seems way more than just the front wishbones,
It feels like the arse is all over the shop....literally doing its own thing.
All my toe in's etc are good, but i know some of my camber is out. But that's been out for a little while already and not felt like it does now.
Only thing which may be to blame is the elite alloys, with they're 225 tyres, instead of the 205's i was running.
Anything i should really do or check other than the Front wishbones.....
rear donuts is it? Are they going to be a PITA to do?
-
its now chipped, lot more torque going through the diff, this does make it twist a lot!! if your donuts are slightly suspect the extra torque will exacerbate it!! :y
-
well thats just it......
I'm talking about driving at a sedate pace....off the throttle....
Just driving in a straight line it pretty much does its own thing....
-
Could be a number of things as omegatoy says rear doughnut bushes or the steering idler,wishbone bushes track rods etc... :y
-
yeah, well i'll get the wishbones done asap, but should i change drop links as well, antiroll bar bushes?
And the rear donuts can be expensive afaik?
Also....besides warped discs, would the worn wishbones cause brake judder?
-
Speaking from recent experience, if you think the rear w/b bushes are "code F", I think you'll find that the front ones are just as bad if not worse. Too much slop in those and the toe settings will wander about all on their own, I think. I'm no expert on geometry though.

Try your old wheels back on and see if improves, could be the tyres on your new wheels causing some of your problems,wider tyres will tend to tramline more
-

Thats what I was thinking... 225 (Shouldn't they be 235?) tyres will have less give in the sidewalls so will cause the car to handle differently.

Facelift elite is 235 but I think earlier cars run slightly narrower
-
Yeah they are prefacelift elite 16" allys, so tyre size is 225/55/16, that is standard fit.
It may be them, so yes, first port of call would be to change them back and see how they feel then.
And then i'll get wishbones done.
And whatever else i can replace....dont fancy doing donuts as i hear they are awkward and i've done enough to this car already.
Just seem to be throwing money at it lol :o :-/ ::)
adding the chip, allys and leather was my choice tho....
Waterpump, new coolant, 2 oil changes, and new filters all round weren't though.
damn bushes and geometry.
I think thats what its going to come down to.
elite allys may have put geometry out of whack more or something. Considering its already naffed.
-
I put new tyres on mine as the old ones were gone on the inside edge, absolutely terrifying steering with the new ones on until I got the wishbones/track rod ends done.

Get used to it ;D

You could also check to see if the wheels/tyres you have fitted are on the right way, are the tyres directional, are they turning/running in the right direction?

Funny you should say that, as the off side rear tyre is the wrong way round. I did notice, but i had picked the best of a bunch of wheels from Darth Loo knee, and ended up with 1 odd one.
You really think that will make such a profound difference?

Fair enough,
dont think i've ever had a car that needed such precise set up to drive in a straight line LMAO
;D :D

Isnt it worth a try, especially if the tyre is directional? Better to try the simple things first instead of throwing monety at it, only to find it may have been a simple five minute fix?
-
Is it the elite? If it is have you considered knackered rear shocks? When mine went the car was all over the place
-
No it's not an elite..It's a select, with elite alloys and leather ;)
As for changing tyre...still going to cost me a tenner just to change the direction of it on the rim.....
So still chucking money at the problem, but yes, probably worth a go, as the rain clearance is compromised if its facing the wrong way
-

I totally agree with that, I had one fail on my Senator and it was all over the place even on a straight road, it would just wander constantly.
-
Thanks,
Worth bearing in mind.
Back right hand side is creaking quite a lot too.
Sometimes stops, but its there right now. And if i grab the car by the roof rails and rock it, then i get the squeak, squeak you'd expect.
I take it this is further evidence of rear bushes?
I dont fancy changing shockers as well......
Sooner be selling the car than spending money on replacing every component lol.
-
rear shocks are relatively cheap for non self levelling but check to see how it settles after giving it a rock at the back end and have a look for oil on the shocks, i would say changing the tyre to the right way well that just should be done as a matter of course in my opinion!(i wouldn't write the car off for a tenner!!) but i hear where you're coming from with throwing money at an old car but i'd say this once you've got it sorted then you should have a good car that should be relatively problem free for a while (well that's what i'm hoping anyway!) so i would say at this point stick with it and get it right and you'll soon have it handling right and then you can enjoy it, i come home from work in mine throw the cruise on and sit back and relax i think it's a great car even if it's old and not the most beautiful on the road!!

well that's pointing to donuts just do them pita job but once done i'm sure :) :) i'm not really sure if mine need doing but when i have the time i'll do them and have peace of mind because i'm sure when these cars are properly setup they must be the ultimate cruiser!
-
You're certainly right about it being a great cruiser.
on the 1200mile round trip to scotland i just did it was great.
Happily sit at good speed and still have enough poke to overtake without changing down lol.
As for rear bushes. I'll get them ordered, and maybe do them the same time i fit the new exhaust middle and back.
(Be a long day....but i got a chisel and a hammer handy if i need em.....
At least they are only £28 for the pair delivered.
Front wishbones as well....and then tyre swapped round....and then WIM setup....should be spot on then....
I fancy lowering it on springs tbh, cos it rolls a little too much for my liking in the twisties, But they maybe helped by fitting new Antiroll bar bushes too, or poly bushing them....
tempting. ::)
