DII Steering inaccuracy, not wobbles, not shimmy

[robertofollia]

Hi all, just to make a long story short, my 99 DII v8 5 speeder wants to kill me after driving me crazy. At 50-60 Mph (or between 80-100 Kmph), whenever I step on the gas pedal or back off the throttle, the truck changes lane in less than 2 seconds (i floor the gas pedal, in 2 secs changes lane; i back off the pedal and in 2 seconds comes back to the lane) both in a straight line and in a highway bend. Have been living with this for 1 1/2 years and have performed the following repairs/upgrades to no avail, and lately things have worsened a little bit, as when coasting it seems as if the truck front end was drunk.

-All bushings and suspension components are 1 1/2 years old (even the rear watts linkage ones)
-Steering bars, drag links, track rod and its ends are 3 months old, and are nice and tight
-Tires are 1 1/2 years old, properly balanced
-Steering is balanced. Steering feedback is perfect, no wobbles, no shimmy, no shaking, better than new (when I changed drag links and TREs)
-I lifted the front axle and could not feel any play both in bearings and ball joints.

Please point me what to look at before I set fire to it. The only suspect parts might be the steering balljoints in axle and front bearings, and the worst new is I will have to take it to the stealership, as I 've taken a look at the Rave and balljoint renewal is quite a PITA and no local workshop wants to mess with D2s particular issues.

Thanks for your input and happy Sunday to you

Have you personally replaced the bushings?
What you describe ideally matches one or more of trailing arms bushings (on the frame side) worn out.

Hi P M
it was a double post, I answered you here

I replaced all bushing myself using a decent press, took me ages to do but did not leave any to replace, did not want to be cheap there. But.. it's just crazy.
Will report news in the other post.
<what I don't want to do is begin the crazy replace-all-parts-syndrome-and-the-issue-stays, so typical of our rovers....

Best regards from the other side of the pond

Check pandhard and watts? most of my play is in that rubber coupling.. its not front end so much as steering linkage looseness
