Knock/Dragging - Fixed/Figured out.

Post by CBA » 25 Mar 2010 04:32 am

Hi, First post here - Just bought a bit of a dog, but lots of MOT and tax to keep me happy. Just this knocking is worrying me - At full lock or nearabouts sometimes it feels like i'm dragging a flat tyre and getting a bump through the steering and also hearing a bit of metallic crunching, also have a wobble at 72MPH - Just wheelbearing or something else? How do I check and test on this 1985 1.4 340?

Could be, check your tie rod ends, the rubber could be perished.

Wheel wobble could well just be tyre/wheel balancing

there's absolutely no play in the steering, I can "RAG" the steering lkeft and right and no creaking/knocking -
Noise is worst when reversing or on uneven ground, have to stop being lazy and get it jacked up :idea:

Sounds more like you got something bent at the front and its rubbing on the anti-roll bar. You don't want to jack it up just stick you head under and turn the wheel to the point where the dragging occurs.

Check the bottom swivel joint for straightness, the radius arm mounting and the front suspension crossmember, although it is hard to tell if this is bent. Also check the spring cup has not detached from the strut, although I think you would notice that all the time.

Also for more serious problems look inside the wheel well beside the radius arm mounts, if there are any wrinkles the car is scrap. I've posted some photos of this on another thread, cause by joyriders crashing over curbs.

Right thanks for that, much appreciated - the thing tracks/handles pretty straight and true - so hopefully just some consumable
or at least something that I can replace. fingers crossed.

There's no contact between tyre and rollbar, though the rollbar could be bent, looks suspicious.
The chassis mounting points etc are all straight and solid, nothing worrying there - phew.

The tie rods are loose on that side, look very squashed and worn - about 3mm gap at the bottom of the top mounting, cannot be tightened further - where do I get them from?

Also the bearing has play for certain - just a goosed bearing and too-old tyres I think, Is there anything else in the hub/hub itself that can wear out?

Tie rod (Radius arm) Dia (classicswede) does a poly set for £25. I havn't used them (yet) but nice new ones from Volvo really make the steering nicer and more new car feel.

Bearing should not have any play, if that is what is making your noise they are feked and need attention. Yes there is adjustment but if it is grinding it will probably need replaced and you can sometimes just bodge it and replace the outer (small) bearing in about 10-20 minutes if the track is ok. If the track is damaged its a bit harder but straight forward enough if you have some stiff bolt skill and can handle friction fit tracks. I've never seen the inner (large) bearing worn or damaged, but check it anyway.

In my experience bearing problems would not just happen on full lock, would be cornering that would cause it. Guess if its really bad the disk might hit the calliper.

The hub is just 2 bearings on a stub axle, although you need to remove the calliper bracket to get it off (2 x 80ftlbs rusted bolts). To see the bearing and hub nut just pull off the small domed cap, it will be obvious how to remove it and the hub. Then remove the inner seal and bearing and clean it out, you will then have access to the outer track to knock it out with a punch or drift.

The bearing is weird, never had this sort of play before, unless accompanied by the other...
It moves along the axle, in and out, tighten it up and it still moves in and out. tighten it silly tight - moves in and out, I think disturbing it has made it worse too... otherwise the bearing is quiet, smooth and efficient when the wheel is spun.
I'm stumped, going to have to take it apart, wash the lot and see where this play originates.
Getting manual sometime next week off ebay (fiver), and have a lot of bodywork to get through anyway.

off the road for next few days, wings on the washing line... need more rustproofer primer and sandpaper.

Is it possible the last person to mess with this bearing left a spacer washer out...
just thought... the bearing itself seems fine, it spins and is quiet, but the bearing is not held tight, it moves along the shaft so to speak...

how about the bearings under the topmount (don't know the english word for those)

those are notorious for making noises at full lock & low speeds; if these bearings are noisy they are obviously perished but these don't create noticable play in the steering/suspension

The wheel bearing only has an outer most washer between it an the bolt, about 1.5mm thick I think. I didn't think it would cause that, but if the nut is getting tight then maybe it has reached the end of the thread and you do need the washer.

The bolt compresses the outer bearing against the inner one which is braced against a taper on the stub axle. If the inner bearing is split it will slide in, never seen that though.

If you got to the point of seeing the axle nut you could have removed the outer bearing and inspected it, although it may not have told you the problem. I'm getting a feeling its the inner that is the problem.

You need a 17mm 6 sided socket (or is it 19) on the brake bracket bolts, and as long a lever on it as you can get (remove the caliper first..easy). Don't try to hammer on a spanner. The hub+disk will just come off then, very easily. You will see a rotating grease seal at the back, the inner bearing is behind that but you may see the problem without removing it.

If you get a replacement kit make sure you get a new seal and inner bearing, I may have a few unused inner bearings I didn't use.

The wings go back on tomorrow, still need a better coat of paint, but I've done them and the tatty bits for £40 and it looks ok or will do by tomorrow night..
I'll have the bearing out while stuff is drying - Picking up some more filler and primer so will get some grease too, If I find a battered inner bearing I'll give you a shout, thanks!
It has had a bump on this side you know... All kesma/slashed down one side, from back to front, about 20 mph by the looks of it, took out the front wing, one old bolt was still on where the old wing appears to have been ripped off -
Like I was when I bought it... ah well...
The suspension seems straight and the car doesn't pull to one side, you could make a sandwich on the motorway + eat it.
tyres appear to be wearing perfectly evenly., brakes in a straight line... handles properly
just hope something's not tweaked as well as the bearing

Still not found a door glass, It's being put into service tomorrow whether it likes it or not - if anyone has a drivers door glass for a 5 door 340 within 50 miles of bolton, please give me a bell on 07546210573 whenever.

I given my wheel some serious bumps, needing replacement components and had joyriders destroy the front alloys (wrinkled chassis) but the bearings where never damaged. Guess you never know though.

If you are getting grease, don't get the normal stuff, I was told that is too weak for the Volvo (by the dealer). I have always used race/rally spec Castrol BNS. To be honest I've never tried normal LM grease in the bearings.
