Hi all. A few months ago I posted about having a great deal of work done to my 1996 850 wagon and when I got it back had a number of problems occur. One of which was that three of my tires went withing a two week period. All three the tires were severly worn on the inside. They were failry new tires so we did not see the wear until the tires went. Even during the time the car was being repaired and tires rotated, the mechanic ( a volvo mechanic) did not comment on any unusual wear. We ended up having to replace all four tires.
Well last week someone ran a light and hit my poor car. When the mechanic where my car was towed assessed the damages, he noted that both front tires had severe wear on the inside. This is the second set that this has happened to.

My question is this, being that the volvo mechanic that fixed my car back in feb did not notice anything unusual when he rotated the tires and this is the secind time my tires have gone bad, is it possible the mechanic did anything wrong when he repaired my car? Back then I had ball joint repair.
I have a small baby and I am afraid to drive this car now.

I second Tina's opinion. I know that ball joints are on the ends of the control or A-arms, but were these changed? I had similar problems with my 850 once but when these were changed out the problem went away. I only went through 2 tires this way (2 fronts)...never 2 sets. Also, is your mechanic or someone who is aligning your car using the wrong specs? Maybe toe-in is too much.

"Also, is your mechanic or someone who is aligning your car using the wrong specs? Maybe toe-in is too much. "

This is what was wondering. How do I find out?

Okay,
Here's what I found in Vadis for your car (See picture below)
Hope this helps.

BTW, I was wrong about Toe-in. It's excessive Toe-out or negative Toe that increases wear on the inside of the tires. As far as the squiggly symbol above the "n" or for that matter the "n" itself and the "double S" symbol don't make any sense to me but I'm sure they do for someone who knows about doing alignment. If I were you I'd just copy and print what is below and take it to your mechanic and ask some questions.

Good luck!

Hello. Vadis eh? I have a couple questions. :)

I have a Volvo 850 Turbo, with the sports suspension. Are the alignment specifications differant between the 850 sport suspension and the 850 standard suspension? If so, is there any way you could post the two sets of front and rear alignment specs for both sets of cars?

Also, and this is totally unrelated to shocks and struts, but Vardis dosn't happen to have pinouts regaurding the cruise control ECU (1378076)?

Thanks in advance for anything. :)

Made in Japan,

I also have '96 850 GLT Wagon, N/A with a 5 speed. Do you know what the Vadis specs are for aligning the rear wheels? If you do, could you print it, as you did for the front wheels. Thanks in advance.

Hugh

No Problem. Here you go:

You need some alignment work or suspension problems - I'd take it to a place that specialized in alignments and tires like American Tire Company and have them check alignment and balance the tires. If you need to buy new tires you can get them at www.tirerack.com and have them installed at ATC. I recommend the Kumho Ecsta tires for the 850, they are far cheaper than the Michelins and at least as good if not better. I had them on my 850 for 2 years and they still have lots of treadwear left. American Tire Company will also offer you lifetime rotation and balancing which you should do every 6000 miles (not just rotate).

Have the sway bars, ball joints and struts checked at a reliable Volvo mechanicc as well.

Hi Tina. I had all of this checked by my Volvo mechanic in feb... or at least at his shop. I think all of this was replaced... or at least the ball joints and sway bar was. Is it possible something was done incorrectly? The problem w/ the tread wearing on the inside only occurred AFTER the repairs in Feb. Again, since that time, I have gone through two front sets.

Did they replace the control arms? It sounds like a major alignment problem - like MIJ said probably toe-out. I'd go somewhere else and have it double-checked.

If it turns out they did your alignment to th wrong specs maybe you can get them to buy you a new set of tires - write them a letter and make soem noise! You should not have to pay for 3 sets of tires because of their mistake.
