 Subject: rear end hops in turns

Message:
When I hit a bump during spirited cornering the rear will break free very briefly. As soon as it recontacts the rear is well planted and tracks well. Are aftermarket shocks the cure ? What has worked for you ? Dealer says all vehicles do this but it is more noticable than any other vehicle I've owned (many cars and trucks). 2000 RC 4.7 4x4 with trailer package (but I don't think package includes stiffer 2000# springs) I'm not new to 4x4's. I'm tempted to try the higher tech Edelbrock shocks.

You can try replacing the shocks, or just adding some weight in the bed of you truck.
Also, do you have a limited slip rear end ?
Under acceleration, they have more of a tendency to "slide-out" around corners. This is due to the different speeds of the rear wheels when cornering, and the LSD working to eliminate wheel slip.
Also remember, this is a 4x4 truck, and not a sports car. they handle differently.

Trailer pack has a fairly wimpy sway bar on it. Shocks are firm but mushy, springs are made for ride quality. Gotta stiffen up the rear end a bit to keep the tires in contact with the road.
I would try Bilstein(no offense to Edelbrock, I run Bilstein on al my stuff) shocks first, then if you come up short, aftermarket swaybar, and then as a last resort, springs.
New springs will eat up your stock shocks, especially on the rebound, so make sure you have new or aftermarket shocks when you put heavier(stiffer) springs on.
Hop is going to occur no matter what, especially on sharp expansion bumps, but if you put more weight in the back, it will tail out worse than before, and of course ruin your mileage.
Just my $.02.

welcome to the world of stiff rear axels that are not independent. Some of the "hop" you are experiencing can be controlled with an anti sway bar but the only way to get rid of it is to convert to independent rear suspension. Sorry but that is just physics. My dak "hops" so bad over a bump in a curve on the way home from work it scares the heck outa my passenger, When I drive the concorde over the came bump at a slightly higher speed you don't even know it is there.

Thanks,guys. I'm aware limited slips can break loose if goosed in turns,thats the solid rear ends I have in my '69 'cuda and '72 challenger. Rear isn't breaking loose while tire is planted,just a quick hop. I got the regular cab for lighter weight = quicker truck. Don't think dead weight is prefered solution. A truck has been my primary vehicle for almost 20 years, I know they can handle better than this, my '75 W100 had less hop in bumpy turns. Would the Roadmaster active suspension address this issue ?

Converting to an IRS fixes the problem? Hmm, thats funny because most IRS suspensions have WORSE hop, such as the vette and mustang.

my friend i had the same problem with my 2001 dakota
i got one of those spray in bed liners
line-x
done to my truck. the extra weight of it not only stiffened up my ride quieted the bed and i no longer bounce when im making a turn.
although if i hit a good bump everynow and then it does a little dancing but thats to be expected. but fore everyday driving its 100% better overall

I have the trailer towing package as well and I think it does have stiffer springs. Before I got my truck I read in Car and Driver, or something similiar, that the extra stiffness causes that problem and some weight makes it dissapear. I got my truck and they were right. If I have my quad back there it doesn't bump around at all. I think its just the price you pay for having the trailer package cause I really don't want to drive around with my quad in there all the time.

My 99 with the 1 ton payload option really hopped.
These trucks have stiff suspension not like a F150 where if you stand in the bed it sinks 5 inches. If you get the chance watch it from behind, on the bump the whole rear comes off the pavement. My 01 QC isn't as bad as the 99 RC but I think the quads come with the stiffer suspension stock. Shocks may help, I doubt a sway bar would though since both tires come off at the same time.

Check the air pressure in the rear tires. Set the pressure to what is specified
in the owners manual, NOT based on the MAX PRESS. listed on the side of the tire.
When I inflated my tires close to MAX PRESS, the amount of bounce while driving greatly increased.
I noticed that the prssure listed in the owners manual was approximately 8 psi less than
the pressure on the tire.
It makes a BIG difference in handling on the truck.

hey joel every mustang that I know of and there my be some that I don't from '64 thru 2002 have solid rear axels, not irs. and I can show you few early vettes that also have solid axels from the factory. Best I can figure you know not of what you speak. When it comes to handling and smooth ride nothing beats fully independent suspension.

hey no name are you saying you go around corners with the throttle wide open ?????? the only way you get axel wrap is from a dead stop and suddenly applying full throttle. My Dak bounces sideways at certain WIDE corners with a bump in the middle taken at about 45 mph and absolutely closed throttle. When I take my Intrepid around the same corners at the same or higher speeds, hit the same bump in the road, the intrepid does not jump sideways. to pappie1 ALL beatles from the early 60's to the mid 70's had swing axels in the rear, and had 4 wheel independent suspension including the so called super beatle. however the FRONT suspension on them was changed in the 68 models. I worked on the things from 63 till 80 when I when to work for for a Dodge Dealer.

No name - need a suggestion ? I could think of plenty of names for you, it's not axle wrap. The stock shocks are not a good match for the springs. I think BB2DAK's suggestion of less air pressure in rear tires would help sort that out but I don't want to go that route as I often use my truck as a truck and don't want to compromise load carrying ability. I will try to solve the problem with premium shocks. Carrying extra weight also helps but who wants to carry weight they don't need ?

Actually, the principal is the same for both, it has little to do with which end is driven. Bump loads suspension, shock damping is insufficient for spring rate, turn adds sideways momentum, rear end loses contact and steps out. Who's the idiot now ?

um....... nope.... the front from...um 48 to 58 was a link pin front suspention... 58 was addapted a different sway bar and wasn't changed to Mid year 67 where it was changes to a balljoint front suspentionand hasn't change much from design till Nowadays in Mexico. FOR THE REAR .... swang axle until 65 where a compinsator was introdused to help travel.... redesigned in mid 67 only to be scraped for a IRS on 68 to help introduce the autostick.... which where scraped in 70 and remains an IRS till today in MEXICO.
The superbeetles where introduced in mid year 1970 with an IRS rear ,same as a beetle just differnt 3 and 4 gear, and Mcferson Strut towers front suspention which remained with only a minor change in spindle design in mid year 72 and until 79 when it was discontinued
Can't touch me on this. You might have worked on them.....but I collect, restore, researched them. I got my truck to tow them to shows.
BTW turn slower on turns help too. Still hops but its not as bad

hey no-name you little idiot, the cornering effects on a vehicle are not effected by which wheels are driving the vehicle, UNTIL centrifigle force exceeds tire friction. then and only then does things change. Independent 4 wheel suspension will hands down out corner a solid axle vehicle every time and in every instance, The tires remain in a verticle postion, that puts more rubber on the road, a solid axle, when one side gets bounced, the wheel on the other side tilts, removing some of the rubber from the road. nvdak if you were born with brains you lost them on the way to your phsychiatrists office, but joel said that cars with independant rear suspension hops worse in corners, and that just ain't true. swing axles are a very cheap independent system that introduces a host of problems that are in some cases worse then a solid axle. Ford got ir right with the Taurus Chrylsler with the various versios built on the Concorde chassis, and gm on the 'Vette. By the way , if Vettes hop so bad in turns, why do the out handle every thing made in the states except a Viper and that also has IRS. Sound like a bunch of democrates on here, posting as to the way thay wish things were instead of the way things really are.

I have a 02 RC 4.7 5spd and it did the same, it also did this when driving straight and i would hit a bump....the rear would squirm around a little. On a hunch i put on a Belltech rear sway bar and 99% of this is eliminated not to mention the added handling from alot less body roll.

I am trying like hell to find a place to buy Energy suspension bushings but can't find em in North Carolina but I've only been searching for a week. I carry probably 250-300lbs in the bed always and it does the same thing, the shocks made no difference.

You guys have to realize something. It is the nature of the beast when it comes to a live solid rear axle. All cars and trucks with that rear suspension design have that problem. From Mustangs to F bodies and trucks. You can help decrease it by using better shocks,less tire pressure and adding some weight to the bed. You can also try slowing down a little. Remember, these are trucks not Corvettes.
