Bad vibes ?

[dunnin21]

Just got my sj on the road this week, when driving on the road if I go over 50mph there is a strong vibration that shakes the hole anus. It feel like its the front prop iv checked everythink tight and straight there isn't any think I can see. Any one have any suggestions

Could be a range of things. Brakes, props, bearings, steering.

Have you messed about with the suspension much?

Are the wheels and tyres on it balanced?

What sort of vibes?

Like a steering wheel shake/wobble

or

Transmission vibes?

[dunnin21]

Like its coming from under the drivers seat and shakes anus not wheels or bearings. Was thinking front prob might have a slight bend in it or could the transfer box cause it to happen. Seams strange that it only comes in after 50mph

[Jordi]

First thing is to go the whole length of the transmission and make sure all bolts are tight.

Mine developed a hell of clunck a few month back as id ripped the t'box off it's mounts.

Does it do it at 50mph in 4th gear as well as 5th gear?

Yeh in any gear over 50 I checked all bolts yesterday. Do the prop shafts have to be lined up

If you dip the clutch at over 50 does the vibe stop?

The UJs on the props need to be fitted so that the yokes are in phase.

If you pull away in 2nd/drive up a steep slope inder load does the transferbox/gear lever wobble around a lot? You could have a broken engine mount but you will need to remove them to see as there is no other way to tell, it's easy to pull one off at a time to inspect them though.

[dunnin21]

Ill do that next time I'm out. What do you me connected in phase

[Jordi]

If you pull the props apart they need to go back together so the ujs are lined up right. So they all bend in the right place at the right time.

Does that make sense?
