I've been meditating over a Haynes manual, apropos a front left wheel area squeal (definite rotatory component) that's driving me mAd (it only or mostly occurs on acceleration and right turns), and apparently, apparently, there's nothing really holding the inner ends of the transaxle drive- axles, which are splined to tripod- type bearing- spiders (in the inner CV joint), to the tripod- bearing outer race or housing and hence to the transaxle itself, except for the plastic lubricant- holding and protective boot, so, technically, if the stuff on the outer end of the drive axle, the steering knuckle in particular, was busted loose the thing could slide right out. <mull> I'm hoping the squeak is at worst a hub- bearing, since you don't have to pull the whole flippin' left drive- axle out for that. Which you do apparently, apparently, have to do just to replace either flippin' boot on either end (inner or outer CV joint), which sounded totally insane to me the first time I read it, and still does, months later. -- tinmimus99@hotmail.com smeeter 11 or maybe 12 mp 10 mhm 29x13 You want a job and a lizard to ride? < _The Einstein Intersection_

Yes. But the other symptoms (like a flopped-over wheel) would override any axle related problems. > > <mull> > > I'm hoping the squeak is at worst a hub- bearing, since you don't have to > pull the whole flippin' left drive- axle out for that. Spindles hum/growl and are affected by turning forces (e.g. right turn no noise, hum while turning left or going straight) during the early phases. Spindle bearings don't squeal until the bearings are totally trashed and the lubricant is burned away. Usually there are premonitory symptoms that are hard to ignore like loud grinding noises and steering wheel vibrations. If you're persistent, things heat up and smell a bit before the really loud noises start in the terminal phase before lockup and separation (minutes to disaster at most).

They are pieces of thin steel bent to contact the disks. Typically, the sound changes when the brakes are applied (can get louder or go away even) and may be affected by turns as well. Some high-performance pad materials can be a bit squeaky especially during light application of teh brakes. If you're not driving a cop car or something tweaked for the track, this is unlikely. -- nuts

I've a seen a wheel go by, from the very car I was riding in, on an Interstate highway, before. A moment of silence for the Ford Fairlane, that stable tank of a car. (And fairly decent off-road vehicle.) >> <mull> >> >> I'm hoping the squeak is at worst a hub- bearing, since you don't have to >> pull the whole flippin' left drive- axle out for that. > > Spindles hum/growl and are affected by turning forces (e.g. right turn > no noise, hum while turning left or going straight) during the early > phases.

What's a spindle bearing? would that be the hub bearing, the cage bearing of the outer CV joint, the tripod bearing of the inner CV joint, or yet another bearing heard from? the steering- knuckle ball- joint maybe? <looks a little wild> > Usually there are premonitory > symptoms that are hard to ignore like loud grinding noises and steering > wheel vibrations. No no no. Nothing like that. > If you're persistent, things heat up and smell a bit > before the really loud noises start in the terminal phase before lockup > and separation (minutes to disaster at most).

Braking doesn't affect _my_ left front wheel well area squeal. Acceleration is a definite fave. > Some high-performance pad materials can be a bit squeaky especially > during light application of teh brakes.

I started to say I don't use high- performance anything, but then I remembered the Great Concorde 2.7-L Trap, wherein both the owner's manual and the Haynes manual say you can use ordinary rather than high- temperature synthetic motor-oil, and you can't, unless you want to experiment with what happens when yer oil- channels sludge shut (for some reason the timing chain often snaps during the terminal event, sometimes hard enough to blow the cover off). I've read the design was computer-generated-- I mean, for real, not just CAD or preliminary or auxiliary modeling . . . . -- tinmimus99@hotmail.com smeeter 11 or maybe 12 mp 10 mhm 29x13 You want a job and a lizard to ride? < _The Einstein Intersection_
