Notice a shake between 60-70 got wheels re balanced and have had sway bar and tie rods replaced recently. Any insights maybe ball joints?

 

Ive had it happen where a tire was separated. Double check to see if the tires are perfect. When mine was seperated I would balance it but then the shake was still there. Replaced the bad tire and the shake was gone. Is the shake for sure coming from the steering wheel or can you feel it in your *** through the seat? If you can feel it in your *** then its usually driveline related. ive had a bad ujoint that caused a bit of shake. Thats about all I can add other than to make absolutley sure there isnt a chunk of mud or something stuck to the rim somewhere.

 

Easy to check ball joints. Jack up car and shake wheel at 12 and 6 o'clock position up and down.

 

It's most likely your tires or a bent wheel. A rebalance won't fix it, only new tires and/or wheels will.

 

What size wheels are you running? The larger the wheels, the harder they are to balance. I'd say most of the time my 19" wheels haven't been balanced correctly the first time, especially if the guy doing it doesn't have a lot of experience. On 18" wheels I have better luck, but still have run into bad balancing quite a few times. A lot of people make the mistake of assuming just because they got them balanced that they were balanced correctly and the problem must be elsewhere if they're still getting a shake. Do you tend to use the same wheel/tire shop, and do they usually get the balancing right? How old are the guys doing the balancing? Late teens/early 20s, or guys with some experience? Are they also doing a road force balance, or just a regular balance? Make sure they do the road force.

Often the bad balances I've gotten show up exactly at the speeds you're talking about of 60-70 and they're just fine below that (or at least it's very difficult to notice any shake). My record for bad balances was 4 tries to get it right at one shop.

Why would a rebalance not fix it? This is exactly what balancing is designed to do...

If it's a bent wheel, no, balanceing won't fix it. As far as the tire, yes it should unless the tire is not true, in some cases the tire can be so far out of wack a balance won't work because of the amount of rebalance weight needed, spreads it too far out and creates it's own unbalance.

 

I can't recall the tech info now that explains why the most common balance issue speed is about 65mph, but it usually is tire/wheel balance related. I always watch my wheel/tire spin on the balancer looking for up&down or side to side movement that will cause a ride disturbance so I can intervene & solve the problem while still at the tire shop.

 

Had a shake on the steering wheel. Took it to a fellow at the tire store. He jumped in the passenger seat and within 200 ft. he told me the problem was with the tires. He was RIGHT, the fellows at the dealer had all sorts of theories as to why I had a front end shake. Go with the tire guy.
