Kerbed rear wheel.Toe in

[Guest]

Hi all ,I've been lurking on these pages for 2 years,  this is my first (desperate) post.

To cut a long story story short ,I kerbed my rear nearside wheel fairly hard ,but not to cause any serious damage to the alloy,(20 inch).

I had a 4 wheel alignment check ,all good up front and rear offside, however, the rear nearside is now showing toe in ,and is the cause for a slight pull to the left,(about 5  degrees steering wheel deflection to the right to correct).

The vehicle is a fixed beam arrangement ,so has no toe adjustment.

My question is this, what is the likely hood of the stub axle mounting being bent,(needing a new rear beam),or is it possible just the stub axle itself has shifted/bent or the whole beam has shifted on its bushings?

The camber is out too, readings as follows. camber 0.41% Toe 0.35%

Although I hit the kerb with a thump it did not seem enough to be catastrophic,

Any thoughts?

Thanks folks.

Dave.

Hi Dragondrummer,

Our 2007 Alphard was pulling left regardless of road camber. 4-wheel alignment showed Nearside rear (NSR) toe was 0˚05' [OK] but offside rear (OSR) toe was -0˚38' [definitely not OK]. There was no play in the rear bushes and everything looked fine. As you know, the rear axle is fixed, so can’t be adjusted. In the end I discovered that the OSR toe-out was due to a poorly assembled wheel bearing retainer - 2 of the 4 nuts were missing (nowhere to be seen I was told by our mechanic, but not in the hub, where they would have been if they had worked loose / sheared off), so the leading edge of the wheel was facing slightly outwards; not enough to notice initially, but gradually getting worse! There had been no work on the wheel hubs since being imported, so it seems this was a longstanding problem inherited from the Japanese owner, or possibly even from leaving the factory. I don't know if this will be relevant to your situation, but it might be worth checking the rear wheel bearing retainers to see if they’re aligned/secured.

Incidentally, as part of the process, I found two different sets of wheel alignment figures (take your pick…)
