elko88 Posted January 24, 2020 Share Posted January 24, 2020 (edited) Has anyone experienced a pulling to the left upon acceleration when driving at highway speeds? My 88 does this, then corrects itself back to the right when I let off the gas pedal. Everything under the front end has just been replaced then realigned, new tires and all new brakes. TIA Edited January 24, 2020 by elko88 Link to comment Share on other sites More sharing options...

TIA Take a look at your rear control arm bushings. When they get really worn it can make driving in a straight line difficult. 1 Link to comment Share on other sites More sharing options...
FirstGenFreak Posted January 27, 2020 Share Posted January 27, 2020 Make sure the bushings in the caster bars are not worn and that the hole/mounting point in the frame is not flogged out. Went through that before. Bushing needs positive location to be effective. Link to comment Share on other sites More sharing options...

Front end has been completely rebuilt but only shocks on the rear Link to comment Share on other sites More sharing options...

If they are what I'm thinking, those bushings were also replaced and the frame was not flogged out as you say. Link to comment Share on other sites More sharing options...

Mr_Reverse Posted January 28, 2020 Share Posted January 28, 2020 Most likely worn suspension link bushings in the rear suspension. If you have an automatic transmission, just park on smooth level pavement, with trans in park and brake off, have someone rock the truck forward and back while watching the ends of the links at the frame and axle housing. If you see movement more than a couple of mm, the bushings are worn and allowing the rear axle shift and inducing rear steer effects. 1 Link to comment Share on other sites More sharing options...

It's a manual transmission, but I think you're on the right track. I'll take a closer look at it. Thanks Link to comment Share on other sites More sharing options...
Mr_Reverse Posted January 28, 2020 Share Posted January 28, 2020 With the trans in reverse or first, it should hold well enough, but might not have enough movement to make the movements noticable. I made the discovery years ago when a friend was following me and he asked why my truck was driving sideways. I had my 3" body and 3" suspension lift with 33" tires, so was pretty easy to check since I could see the link ends through the fenders. The tires gave me plenty of leverage to rock back and forth. It was a bit sobering to watch the axle and links twisting and bouncing. The lower links have more control of the positioning of the axle and tend to wear a bit more than the uppers.

elko88 Posted January 28, 2020 Author Share Posted January 28, 2020 Thanks for the tip. I'll give it a once over this weekend. Link to comment Share on other sites More sharing options...
Dozzerwd21 Posted March 18, 2020 Share Posted March 18, 2020 I'm changing the bushings on mine for that reason also my brake caliper seems to be sticking on the top piston.Sent from my Z982 using Tapatalk Link to comment Share on other sites More sharing options...
