front end shakes like crazy after 45-50 mph its a 2000 155k miles. any ideas?

 

It could be a lot of things but I'd recommend making sure your tires are balanced and the lug nuts are tight. I've had serious shaking on my truck to the point I thought the wheels were going to fall off...one time it was the balancing and the other time my lug nuts were loose even though I hadn't touched them in 6 months. Like I said, there are so many things it could be but check the simple stuff first.

 

make sure your rims are centered on the hub.... thats the first thing i recommend those rims were true and true nothing bent.. i`ve heard when the rims not perfectly centered that when u have problems.

 

I'd have the balance checked on your tires. You might have thrown a wheel weight, it happens. Is the shaking always there and getting gradually worse or does it start at 45mph and start bad?

 

This happen to me on my older F150, and these guys are right, it was a thrown wheel weight.

 

I had some issues just like this from a set of tires that wore badly. I did a poor job rotating my old set and when i finally did, the truck shook badly..

 

could be death wobble just happens when wheels are out of balance or alignment happened on my lifted 91'.

 

I was going to say pretty much everything that has been stated already

 

If your tires did throw a weight...you should open your mind to this....

If you have at least 33s and no tire pressure sensors then you should try plastic or metal bbs in the tire instead of lead weights on the outside. Some think this is a bad idea because they say it doesn't work or it will damage your tires. Obviously, if you decide to do this, it is at your own risk but here is my tuppence worth from my experience. >>>

I change my own tires but I don't have a tire balancer...I had some bbs sitting around so I decided to try them as balancing media and save a few bucks, too. I put 8 ounces in each tire and here is what happened>>>

The only thing I noticed at first was they made noise when I stopped or was rolling at less than 8mph. After about three months of having the bbs in there I decided to open up the tires and check for damage. The only problem I noticed was the bbs starting to rust (probably because I don't have a dryer on my air compressor) but there was absolutely no damage to the tire....

I didn't want the bbs to continue rusting and clump together so I decided to switch to plastic airsoft bbs. I used the same weigh of plastic as I did with the steel to be consistent in the experiment. The plastic bbs balanced the tires just as well as steel and are much quieter. I've been balancing my truck tires this way ever since and plan to keep doing.

Also, this way of balancing adjusts itself to tire wear or mud, won't fall off like other weights, and are not visible, giving your wheels a cleaner look.

I hope my rambling does someone some good.

 

Hmm I should probably make sure I'm not bring back an old thread in the future....sorry guys, I know most of you hate that.
